yeah its done this since ive had the car, that was the reason i decided to change the tps, i have no cel. it just runs like crap, i thought it may have been the iac valve, but i tested it and everything checks out ok, you think it could be the ignition timing? ive replaced just about everything in the dizzy but the icm, ive done new ngk plugs, so the only thing i can think of would be the plug wires, the ignition timing, or the icm, or i suppose a vaccume leak but i dnt know how to check for them....any help would be brutal...

i have a similar issue on my 94 civic my iac and fitv are both good, i cant find a vaccum leak but i still get idle surge form 200-1200 rpm when warm, anyways i gave up looking for the issue cause i have a GSR motor waiting to be swapped......as far as finding a vaccum leak, you can take brake, or carb cleaner and spray the hoses while the car is running if you hit a hole in the line the idle will change pretty quick

double check your tps...there is always the possibility of slight screw up it happens all the time....I had a pos back-yard built alltrac and could not figure out for the longest why it was still over heating even after a new thermostat...there was no water in the oil, smoking or anything like that. i double checked the thermo and sure enough it had come loose...a similar story happened to me with the same car on that time it was a bolt breaking on a new dizzy button i put on.

Anomoly... check your tps sensor that may help your problem... ive changed mine and calibrated it and it helped out some... but who knows our problems my not be related..
i checked TPS, IAC, with a multimeter, then tried a known good TPS, and IAC nothing changed, i know this sounds strange but you might also make sure all of your ground's have good connection, i dont think it will cause your problem but i have seen loose grounds cause plenty of headaches

rough idle? Timing, maybe a leaking valve, bad fpr?

i dont know how you would double check a tps seeing as how it would throw a code if it were off, so i dont think thats it, is it posssible that i got a tps for an automatic on mistake when i got a 5 speed? or are they even different?...

good job. Thnx for posting after you fixed it too. Fuel pumps happen to sneak up on pdeople, my next guess would have been check fuel pressure.

Idk about your name though, you might b stuck with it, lol.

it damn sure tries... i think it could have something to do with my e.l.d but im nt totally sure.. im almost positive its electrical though.. but finding it is proving to be a problem.. its hard to tell.. its an 88si with a y8 swap, and seeing as how i diddnt do the swap, i dnt even kno what car to research. the wiring is almost the same on both cars w little diff, but the fuse boxes are diff, under hood is 88si, but dash is y8, and electrical isnt my field...
