Ok I got 95 integra gsr and when I turn it on n the morning car starts right up idles good and then when it's on for about 4 mins it just shut off , the idle drops and then it shut off, turns right on again then u drive it and if u stop the idle starts to drop and it cuts off again but when it warm up the idle goes up and down until it cut off again........ Now I have changed the tps, iacv, and nothing even the map sensor, also car was tuned so I took it back to the tuner and he couldn't find the problem CAN ANYBODY PLEASE HELP!!????

Any clues, like CEL?

Anything recently that happened at the same time or just before the problem started?

Air and fuel filters clean?

 

You need to find what is missing when the engine stalls, fuel or spark.

The coil and ICM along with the PGM-FI Main Relay are all susceptible to heat failure.

Because of your symptoms, idle drops until engine stalls, would make me guess it's the PGM-FI Main Relay.

It's the first thing I would look at. 94

ek... it could be something we've listed, or something obscure, but we need feedback from you as to what you've done with the information you've been given; what you tried, how you did it, what were the results.

It's Ok if you don't know how to check something - we can go down to that level of detail if necessary - just let us know. Some require fairly simple and inexpensive diagnostics tools you can pick up at any hardware store, auto store, radio shack, etc.

The more you talk to us, the more ideas we can offer.

Good luck,

Mark

 

I had a similar trouble earlier this year with my 98 RS... It would suddenly shut off on me while driving, & had a hard time getting it to start up again... I found that I had to replace the ignition coil & ICM.
