I got problems. After my car warms up and the choke is disengaged, my car tends to stall out at stop signs, lights and everyonce in a while when letting off the gas to make a turn. The car is idleing at 500 and 1000, it just seems to pick and choose where it wants to. also, it is taking forever for my car to start in the mornings, its as if i have no fuel in the lines at all. it takes about 15 stomps on the gas to get it to fire. It is fine for the rest of the day after that. Any ideas???

 

do you have a carbed eng or EFI, when was the last time you changed the fuel filter, checked timing, tune-up, did this just happen recently after you got new gas. there are a lot of things that will cause this. give me some info and i will try to help. good luck, G.L

 

"the choke is disengaged"

that would be the 12a bro.^

 

definately a 12A, will try fuel filter. Have owned car for over a year now and havnt done that yet. Might as well try

 

could be a vacuum leak

 

Adjust air mixture screw until it idles at 700-800 rpms. Mine did the exact same thing

 

This is all about spark. What condition are these items in?

• distributor rotor
• distributor cap
• plug wires
• spark plugs

If you don't know for sure, replace all of it. Next, pull the ignitors. Clean the mounting pads on the distributor itself with some Scotch Brite. Then clean and scuff the metal surfaces of the ignitors themselves. Blast the ignitor connectors from the wiring harness with some brake clean and then apply some Radio Shack Heat Sink Compound 276-1372a to the metal base of the ignitors and re-install them.

That should cure the problem. It did for me. It will still drop to about 400 rpm momentarily when the choke disengages early on cold days, but it no longer dies.

 

I had the same problem, IMO your "Shutter Valve" is sticking, I'll bet you also have the engine surging at constant throttle position. Do a search its an easy fix, I put a bolt in the hose under the airfilter for now, changed the car completely.

 

Can you say HOLY **** BATMAN! It actually worked. Covered up the vacuum hole inside the breather and wouldnt you know it worked. Smoothed out the idle and it doesnt die now. This was by far the easiest fix i have ever made. 10cents worth of duct tape. hehehehe

 

Never ever ever ever ,, ever ever,,, ever ever, push the gas pedal trying to start it, that is a NO NO. flood the engine out if 12A.

anywase good luck with you engine! and duct tape.. : )

batman has a rotary, how do you think he gets that flame so big!

 

Actually on a carbed motor you do need to tap the gas most of the time. When you tap the gas the accelerator pump drops a squirt of fuel into it. Without taping the gas only the air passing the jets causing a vacuum pulls fuel into the motor. Flooring the car only allows more air to pass and more vacuum. So other words you will have to pump the peddle allot of times.

 

not when its spitting out oil. youll foul out plugs on this paragraph. (im not being an a** or anything. or not trying)

it sucks when having to blow those spark plugs off with an air compressor.

You probally need to get a new fuel pump if your getting problems with fuel not getting to the carb. you should have plenty of push on that fuel pump

Edit- I just realized I disconnected the fuel pump relay.
maybe thats why I dont have to push the pedal in.. I dunno all I know is when i turn the key to on, not crank the fuel pump starts a pumpin.

 

This in completely incorrect.

There is no oil being spited out. If you are referring to the OMP the amount of oil this "dribbles" into the chamber is so minute you would have to pump this oil for about 2 weeks to flood the engine of oil.

The fuel pump is only to keep a constant 4psi on the carb rail this has nothing to do with it pulling fuel into the motor.

The 12a SA and FBs run an electric push style pump that all turn on when ignition is switched to ON.

 

How da heck do you foul out the spark plugs???

im being serious now, serious question
nick

 

boy do i feel like an idiot right now

 

Deposits build up, burning to much oil, puting ATF in your motor. So yea oil can foul them out but the oil coming from the OMP is no where neer the amount to foul a plug. The OMP is also based on throttle position. A pump to spray gas from the accelerator pump, if it even does put oil out it will be the amount of a pin head into the chamber.

I had a 13b housing next to me and I am taking a picture of the OMP injection hole. I know its a 13b but it will give you an idea of how much oil is actualy dribbled into the motor.

 

its doesent inject any oil when you pull the choke?

 

no

 

lol sitting right beside ya...Got a rotor in your bed?? JJ!!!

but seriously thats a small hole!!! and the stalling ...could that not be a fuel filter?....

 

when mine was stalling out. the fuel filter from the gas tank goin to the lines was messed up. so much gunk. So the fuel lines were clogged with gunk. then the fuel pump was replaced and sprayed some carberator cleaner into the fuel lines , then sprayed them out,,,, talk about nasty. and now the fuel filter fills up like its supposed to in the engine bay.

 

You know I have never seen or had one stall from a filter. It could happen yea, you normaly get bad hesitations.

 

Fuel filter will not cause stalling at idle, fuel consumption is too low to empty the float bowls in the carb. Most times fuel restriction problems are only evident when the throttle is at or near WOT for more than a few seconds. Even in situations where fuel flow is 1/3 to 1/4 of norm, you'll never notice unless you're driving hard.

As for the 'shutter valve,' if you don't have to pass emissions in your state you'd be well served to remove all the emissions solenoids and vacuum hoses. It cleans up the engine bay and makes troubleshooting problems a whole lot easier.

 

Well if you got dead mice in your gas tank ;-) and they like melt apart they might clog your fuel filter all the way up stalling the motor. So it is posible :-)

 

when you restore a car that has been sitting in a field for a year. and it got rained on and everything else.

mine and dont get me wrong had gunk in the fuel filter coming straight from the gas tank. its possable Ice blue, I know what im talking about on this one.

rust
dont know how it got there dont really care I just know it clogged up my fuel lines
and the dude talking about fuel restriction, that is what im talking about

you could poor gas in the carb and it would fire up and run a little.

but when you touched the gas at all it dropped severly.


Also the crappy gas they had selling for a while after katrina really crapped up peoples fuel lines. We spent a 1000x cleaning out peoples fuel lines and rails

 

Oh yea I know dood I was being serious!
Holy **** dont reminde me! OMG I cant tell you how menay times I filled up my FE and had bad gas, I went like 4 gas tanks without being able to rev above 3k because of detonation runing 10.0.1 compression rotors. I was about to park it and start buming rides.
