6G Celicas Forums

totally found you on the toyota fan page on facebook... hahah

That's awesome. I love this car that much that my profile pic is her! My friend just wrecked her celica, and I get to farm it for parts, so I get the dizzy tomorrow!

I can't find a new one, so I suppose i'm screwed lol

I'm going to end up buying one from autozone. I get a discount there, plus it's cheaper b/c of the core.

So... the distributor didn't fix it. Still does this. Any ideas?

When mine was like this, it ended up being the distributor...but I spent months fixing other things before I found the real issue. It would get better as I go, but not completely fixed. Possibly you have the same issue.

Check your TPS gapping, and make sure it is placed correctly on your throttle body. I had that issue and had to replace my position on it, even though your engine is not the same, i'm can assume they function in the same matter...

I changed fuel filter, plugs, wires, and distributor. I checked fuel pressure on the top of the filter first to confirm it wasn't fuel, it appears you have spark, but your timing may be off. I would confirm the basics first...fuel, air, spark. It could also be as simple as a sensor being bugged out from past research, or a simple skipped tooth or broke tooth on a cam gear. Or, you just didn't put your distributor in the correct position...which I can't explain how to do, but I'm sure effects timing and such, which requires a timing stobe to correct...? Sorry, just throwing you some ideas! Hope they help.

At this point, I've pretty much narrowed it down to something between the distributor and the ECM. It's throwing codes 12 and 13, so I'm getting intermittent spark, and when I'm not, it shuts off fuel. I've replaced the distributor, so it's gotta be a problem with either the wiring, or the ECM. I'll replace the ECM, and if that's not it, I'll replace the harness. If that doesn't fix it, I'll save up for a dang 3sgte, lol.

Does the problem happen at idle or after you've driven it for awhile ??

12 and 13 Code- Distributor or ECU could even be the wires that are bad

41 Code- Faulty TPS Sensor not functioning properly, when you get the idle problem again unplug the connector from the tps sensor and see if that helps, the car will run without it connected too btw but it would throw the check engine light though but if it runs better you know thats your problem.

Dont just start replacing parts thats the worst way to diagnose your car.

I'm not going to just start replacing parts. I've just already replaced the distributor, and it's still throwing me 12 and 13. It's not throwing me 41 anymore, which is wierd, and it's not throwing me 14 anymore. I"m going to replace the ECM next, because that's all I can think to do.

And now it's not throwing code 12. So I just have a single code 13. Seeing as the distributor has now been replaced, it seems like it's either my ECM, or the wiring in between the two. I'm thinking I might just see if it's the wiring by running my own wire from the dizzy to ecu(only in the circuit that it says is faulty.)

the distributor wires are run in a sheilded cover.
you can test continuity with a multimeter between the distributor connector, and ecu plugs to check the wiring.

Alright, I'll try that. Thanks!

continuity test checks out great for every wire, including those from the igniter to ecu. So that leads me to believe the ECM is faulty.

if your GT is auto i have an ECU hanging around ill sell you

standard, but I already ordered one. I popped open the ECM top, and found a leaking capacitor, spreading it's electrolyte to everything within a 1 inch radius, so I think I found my problem. New one has been ordered, and will be here this week.

Interesting find! - I would love to know what caused that =P

my 92 lexus had the same problem.. electrolytic caps just go bad after a while..

Yeah, I'm glad that I have finally found the problem though. I'm sick of being stuck in the middle of the road, having to call a tow truck and someone to pick me up. It's really embarassing and aggravating.

I don't want to jump the gun on this, but I got the new ECM in, did a few test runs, and it seems much happier now. No RPM flickers yet.
