    sudden rich condition, code 11, fixed by EFI reset

    I finally got some follow up information: I fixed the timing. To my surprise, it was set 5deg too late. I reset it and the spark advance was working. The car drives about the same, I think. I haven't solved all the problems, but I think I have the spark working well, and I can rule out...

    great job. Mine's running great also. Mine was grounds, several of them, tps adjustment, and timing.

    sudden rich condition, code 11, fixed by EFI reset

    Interesting. i wouldn't have guessed that. I will do so. For posterity: forget all the cold/warm issues with idling. It turns out that the idle instability occurs within a certain RPM range. With no tach, im just guessing it's around 2000 rpm, very narrow band, then steadies out above or...

    sudden rich condition, code 11, fixed by EFI reset

    More driving, still the original issue with idle, though it is now drivable. Unstable idle: > when cold: Now it starts and idles well, but smells very rich. > After a little driving, not warm yet: it starts holding a higher RPM after revving and laying off the throttle, then after about...

    Code 51

    I just wanted to let you know that my car is working pretty well now after I adjusted the TPS and Idle set screw, did the ignitor upgrade, seated my plug wires better, and most important fixed some bad ground wires.

    sudden rich condition, code 11, fixed by EFI reset

    I completed: 1) new ground for fuse block Observation - it was very rusty and poor contact 2) ground under intake manifold for ECU, add redundant ground wire Observation - bolt was never tightened, my bad. the white/black ground wire wasn't even attached. 4)...

    Code 51

    Thanks, I want to double check the TEWD to see if there are any other electrical parts that might be affected by an engine swap, since I also have a na-T swap.

    Code 51

    Just out of curiosity, what relays or switches did you add or swap when you did you engine swap, and which are still from the original body? Any parts attached to the engine that were taken from the NA engine? Thanks.

    sudden rich condition, code 11, fixed by EFI reset

    Thanks for the flood of great help everyone. To make this more readable this is my summary: Code 11 is no longer showing after some fussing, and may have been unrelated. Still could use help: 1) finding the great procedure for callibrating the TPS. I will now check/fix in this...

    sudden rich condition, code 11, fixed by EFI reset

    This is a great idea! I didn't know that the CPS could specifically affect one coil pack. I may have to break out the scope, but it is a serious, high end oscilloscope for electronics bench work, not car repair, so I'm a bit nervous to take an expensive, pristine piece of equipment into the...

    No Spark, but everything tests good

    I'm not making much progress with mine either. Similar symptoms, though mine was running pretty well for a week. Now I'm not driving it because it got worse. I haven't gotten any responses to my thread so far, though I'm still hoping someone will be available tomorrow to help. I wonder if you...

    sudden rich condition, code 11, fixed by EFI reset

    I'm just thinking out loud, I guess. I also found an extra plug, matches the EGR Temp sensor, which TEWD shows as CA only. Since the engine is JDM with EGR parts taken from an apparently non-california '87 GTE, I'm going to assume this doesn't matter. Checked TEWD. I have fixed all the...

    sudden rich condition, code 11, fixed by EFI reset

    Okay I did the ignitor upgrade, cleaned the grounds from the battery to body, head to body. coilpack to coilpack ground wire to head, checked plug wire order and put rubber inserts in the hollow of the plug wire at the coil side to make even better contact with the coil packs. connectors all...

    car is intermiitently missing at idle

    sounds exactly like mine, but my codes haven't been consistent. Wish I had some answers, but I feel your pain. I'll let you know if I figure it out.

    sudden rich condition, code 11, fixed by EFI reset

    Funny how things seem clearer on a sunny morning. After browsing around, I realized that this is kind of a dumb question until I check all the grounds. Sorry, I'm doing it and will post when I have results.

    Rack&Pinion not working!

    I rebuilt the whole rack and valve with the toyota rebuild kit. It was not terribly hard, once the rack is off the car. with new, clean parts, its not a bad job, but taking it off caked in grease and grime without a lift was pretty bad. In the process I found some of the rebult racks are not...

    Sorry for the long post. Looking for help prioritizing the troubleshooting process, don't expect anyone to figure it out for me.

    sudden rich condition, code 11, fixed by EFI reset

    I have narrowed down a problem and not sure what would be most productive to do next. I had multiple problems originally, so I'm starting this thread now that some easy ones were weeded out. Problem: Car starts great, runs a variable amount of time - seconds to 1/2 hr. then suddenly...
