I used some this morning when I was filling up my tank. Within moments of pouring it in, I heard my idle drop. Driving was a nightmare, it seemed to have no power at all and does alot of sputtering and popping. My first thought is that it clogged the fuel filter, but so fast? What has this done to my car?

devitek

Alright, I'll add to this a bit. Is it possible for the cleaner stuff to cause a vacuum leak somewhere? I'm not finding any similar situations in the archives so far. Any thoughts?

I wonder if it is just a coincidence. It sounds to me like maybe you lost your leading ignition. That would cause those kind of problems.

devitek

it could be coincidence, considering the TT. but i think it would have to be extreme coincidence. i had the car running as i was adding the cleaner, and that's when i heard the idle change. i can double-check the ignition by switching back to stock, but i suspect it's something else.

I wouldn't say he lost the leading ignition altogether, but more like its just breaking up very badly. It most likely is just a coincidence because I have use fuel injector many times and never had a problem. My car ususally runs better after I used a full tank of gas with some in it. But this isn't my rx-7 either.

Its possible the cleaner loosened something up in the gas tank and clogged the fuel filter. I would try replacing it first.

My guess it was a coincidence. It sounds rather unusual.

Question what brand di you use?
And second why are you using fuel injector cleaner, did you go 13b or fuel injected?

Whenever I use fuel injector cleaner on my 240 you can feel a noticable lag in the car like its down on power. until I use the whole tank of gas. So that part is some what normal.

How much gas was in your gas tank?

devitek

I think the stuff is like B-12 Chemtool or something, but I do have a carb. It's just a general cleaner, for all applications.

I think it's most likely that it clogged the filter. The other day, when I was setting up the TT, for awhile I was running on just the trailing and was not having this kind of problem. I don't have alot of time today to work on it, so I'm trying to narrow things down as much as possible. There was about 1/2 tank when I poured some in, then I topped it off. I didn't use the whole container, which is like 15 oz. , maybe half of it was used. I guess it's possible that it knocked something loose that quick, but it just seems odd.

I'd have to agree with gsl-se addict. My car had the exact same symptoms at one time (low idle, popping, no power). Replaced the leading ignitor, problem solved.

the cleaner could have loosened crud in the tank which has now clogged fuel filter / fuel line / injector. we used to blow out the lines with compressed air when this happened.

devitek

Let's assume that it is the leading ignitor. Where do I get another? And how much?

IF the leading ignitor is your problem, brand new ignitors aren't cheap, but maybe you can snag a used one.

Well, since you have the TT, it would be the 2nd gen ignitor that is probably bad. The 1st gen one should be fine. Just switch back to stock ignition and it should be fixed. For the 2nd gen coil packs, you don't see the ignitor separate too much. You can pickup another 2nd gen coil pack or if you are lucky, you can get an ignitor that someone cut out to do the regular 2GCDFIS. I think most people toss them when they cut them out, though.

I think Ican get either one for you just PM if its the J109 I havwe a couple laying around if itsthe 2nd gen I can get it for you. Let me know.

Try switching the leading Ji09 with the trailing and see if that makes a difference if it dosnt then I guess its the 2nd gen ignitor you need.

devitek

I'll check this evening and let everyone know.

If it is the 2nd gen ignitor, am I going to go through one of them a week? If so, this mod may not be effective for me, since it took me six months to locate a junkyard that had just 1 2nd gen. I dunno, feeling skeptical now...

when my car was still carburated, adding fuel system cleaner to the tank would clog the fuel filter almost immediatly. the stock filter sucks its really small.

what I did was extend the rubber fuel lines around the filter and adapted a huge Ford fuel filter instead of the dinky stock one.


or you could get the tank rinsed.

devitek

Unplugged the TT, went back to stock, and it's running normally again. Looks like another blown 2nd gen ignitor. Who said they had a spare?

I will see if I can get one for you tomorrow.

Sorry to hear that you lost the ignitor. The other guys that had problems had failures after like 3-4 months. I guess it depends on driving style and the condition of 2nd gen pack was to begin with. It seems with the basic TT, it is better to operate in higher RPM. It is idle type conditions that really tend to cause the heating issues. This is why it is important for us to get the circuit with the pulse limiting working correctly. It will save us from these problems. For you, I would just wait for the new board before reinstalling. The other option for people who want to run the simple circuit would be to add an additional ballast resistor to the coil power. We would have to experiment with what value ballast would work the best.

devitek

I was thinking about the concept of the ballast resistor last night, wondering if it would make a difference on these. I was a bit angry last night once I found that it was the ignitor that went, and I ended up pulling the leads off the J109 (just used blade connectors) and didn't tie them up...long story short, I burned up the wire from the original coil to the TT in a nice puff of smoke, so I probably won't be using the simple circuit anymore.

I imagine it will take a little while for the circuit board to ship, so Rx Seven, if you have a coil pack just let me know. The only downside now is that payroll double-garnished me for child support and I have no money for about 2 weeks, but maybe we can work something out?

JustDoug

Your location says "midwest"...are you near St. Louis, MO?

I'm gonna scour the local salvage yards tomorrow. Don't recall the year/model, but I seem to remember a 13B sitting in a yard around here.

I am also on the lookout for J109's- they are now part of my "add to stockpile" list. I'm currently running without trailing ignition...

devitek

I'm closer to Kansas City. We were going to hit the junkyard today, but with freezing weather and rain it just didn't seem like a good idea. If it's a little nicer tomorrow, we're going to give it a shot. I'll keep a lookout for the J109's when I do, as I know there is high demand for them around here.

devitek

Ok, just went to the local pick 'n pull, and they had 0 RX-7's out there. They used to keep at least one or two on the lot, but it's the worst I've seen it in years. Anyone else have that problem?

Needless to say, I didn't find the coil packs there. I might try some other yards next weekend, but I'm not hopeful at this point.

JustDoug

Yeah, Pick-N-Pull recently bought out one of my favorite local yards. It looks to me like they tend to "play the numbers" and only buy standard cars which have sold millions. Which of course sucks because I've got a collection of odd old **** that breaks frequently, so I'm always in the junkyards...

devitek

Well, I guess that means I should be prepared to travel to get parts from now on. I've got a friend here who thinks he might know of a local yard that specializes in imports, just have to wait to see what comes of that.

In the meantime, if anyone knows where I can get a coil pack it would be very appreciated. I just got a new VB catalog........over $500 bucks to get both the coil and the ignitor! I don't know if I stated it before, but money is really tight for a couple of weeks, and I'd really like to do some testing with that R2 on the TT to see what is going on with it.
