Alright , this has been happening over the past couple days after I poured some Seafoam. The car started fine and drove fine after it and went to school.Coming back from school the engine sounded differently, at first then went on to normal so i just htought something was cold and got heated up so it went back to normal. But half way home it started giving me the same noise and it seems like it was going to die if I took my foot off the pedal. Sure enough it died at an intersection with a cop behind me, i was scared to have it reving too high so i tried to slow it as much as possible. tried to crank it would crank up so i had to push it into the closest parking lot, from there i kept on going at it for a good 5 minutes and she cranked back up again but now sounded normal and idled normal.

Before i got home i thought i'd give it an oil change not because of the problem but because it was dues for one, but looking under that car i noticed the fuel filter pretty dirty so I started thinking that it could be a combination of that and semi fouled plug from the seafoam because i haven't cleaned the plugs yet. So once i get home I change the fuel filter and i took out the plug and clean them up, crank it up and she fires right up nicely, i decided to take it around the block to see what would happen and nothing happened everything was fine. Later on that day I had to drive to work and half way there that same thing started happening. getting off work though she was fine all the way back home.

The whole next day she drives fine again, but today afterwork she did the same thing again? Anyone know what this could be, i know its a long story but I wanted to explain as best as possible. When it did it today i pumped it a couple of time started it and she was warming up nicely at first, but as i was scraping the windows, she started to sound like that again and then it just stalled before i hit the drive way, and wouldn't crank up again just like it did at the intersection, after much trying and spraying a little wd-40 to help it burn easier she cranked up and now is parked.

 

re reading it i guess i should explain the sound a little, it sounds like its "brapping" slower almost like when it did when i was running on one rotor, but i did compression and all was well.

NOw the only thing that i can't think of is would it be running too lean? when i last took it to the dyno, it was running a little lean in the low rpm and i actually get a lean "kick" when i rev it. So i'm thinking could the colder weather be making it run even leaner since it denser air passing in?

 

How did the plugs look? Were they all a nice tan color or did some look different than the others? The Seafoam should actually clean the plugs up, not foul them.

While the carb may be running leaner, it almost sounds like the ignition is becoming intermittent, or the carb has something floaing around in it that plugs it part time.

Btw, the shell is finally going in the shop tomorrow, if my help shows up. Electric motor for the compressor is still in the shop for repairs, but I can start fitting doors and fenders. Should be ready in about 2 weeks so warm up your checkbook. lol.

 

Hey Scott,

I thought seafoam fould the plugs but i guess not, the plugs were actually black, they had more carbon deposit than normal, i pulled them out about a month ago to check on them and they were always tan brown unlike now, I'm going to recheck them tomorrow.

The more i play around with there carburators, the more i really want to go Fuel Injection, I've actually been really considering the fuel injected webers but I'm not sure how that will work with the supercharger that I have planned. O moght have to talk to Aaron about this alittle more.

So the estimated time for finishing my shell would be? You should send me some update pictures

 

anymore opinions on this? I'm going out there right now to recheck on the plugs, and maybe take a shot of them

 

Alright coming back from outside, I checked the plugs, they're starting to get a black coat on them. I started it up and yup pretty rough again, it sounded like it was back firing quite a bit, so definatly running rich somehow at low rpms now. I haven't touched the carb or anything though but i'm woundering if the seafoam actually cleaned up the carb hence shooting more fuel, plus new fuel filter better flowing through the lines?

 

Seems like you've done everything but cleaning the Holley. I love the Holleys but they do tend to act up now and then. What Holley are you running? Are you getting a good streamline of fuel out of the squirter on both sides? Hows the fuel level in the floats? You might need to clean out the jets and the the little airhorns on the throttle body of the Holley.

 

465 4 barrel RB version ..

 

I would clean out the carb. They need it everynow and then. What kind of coils are you running? My friend had a bad coil when it starting acting up like your car. Good luck.

 

still running stock ... I think that I still have a pair laying around from one of the parts cars, i would check on them, but only if the car would idle for a bit now .. when you say clean out the carb, how far should i disassemble it, just the 2 boats on the sides?

I've only taken apart one carb before and that was a nikki carb

 

Well the Holley is alot easier to work on than a Nikki.
Better have the gaskets first before you do anything.
I would take the carb off the manifold and take it apart. The float bowls are only 4 bolts each with gaskets ( these tear easy ) and the jets are on the primary side. Watch out for the little O rings that are on the fuel tube to the floats. They rip sometimes. Just clean it out good with some carb cleaner and air if you have an air compressor. The squirter has a little metal slider underneath it so make sure you don't lose that. That could just be dirty as well and need a good cleaning. Then there is gasket between the throttle body and throttle plate. If your secondaries are working fine then I would leave the secondary vaccum part alone. It really isn't that hard. Just take your time

 

PM sent

 

Pick up the trick kit for your carb before you take it apart. The kit will have reuseable bowl gaskets. If the carb has never been opened up, it's a pita to clean off the oem gaskets. If it's an RB carb, it may not be so bad.

Looking at 2 weeks on the shell, just in case I run into other problems, like the wipers went nuts on the 2nd gen and 3 different wiper switches haven't fixed the problem. Changing the wiper motor is todays project.

 

Hey,

Alright so i decided to do something that i haven't done in quite a few weeks now and its to ride her hard, my driving lately had been up to 3,500rpm shift, trying to save on gas money, but i just took her out for a good 1/2 and hour 8k shifts, at first she fast puttering and everything once i got up there, but a few wide open throtle runs, she was back to normal now i think, i took out the plug and they're now all tan brown again and not black so I think it just needed a little bit more attention if you know what i mean.

Hopefully she won't quit on me again. I really love her you know, but i think she might be getting jealous that there's been one too many girls riding in the car with us ... sniff sniff ... or maybe it just my shell getting jealous of the other one thats coming so she's messsing with **** in the engine cause she knows i'm swapping that. Lol

Gotta love the electronics on the second gen eh Scott

 

Sam, I thought by now you knew a redline a day keeps the carbon away, lol. Once the plugs start fouling, they fire with less oomph and the carbon builds up even more.

This is the 1st electrical issue I've had with the 2nd gen in the 6 years and 30k miles that I've had it. The reliability I've had with the car has spoiled me.

I've been thinking about doing a writeup on the shell as I put it back together to give others some tips on assembly and fitting body parts. As usuall, I will be taking many pics. We need to finalise which parts are going back on the shell, but we can cover that through PMs.

 

Hey,

Ya i know about the redline just neighbourhgs have been real buggers lately about calling the cops ... really wish that I could just shut them up, and i'm really not getting any support what so ever from my folks, my dad hates the sound, and keep on telling me to trash it ... ah if he could only have a little more faith in me sometimes.

I'll send you a pm later on tonight hopefully about everything (or atleast everything that i can remember at the time).
