OK guys im REALLY stumped on this one. Ill start with some background info.

1992 civic HB w/ 1998 GSR swap
few boltons including sk2 IM, AEM fuel rail, DC headers, ect..

Car is tuned on Crome Pro via a P28 ECU.

The problem is when im driving and put in it nutural to coast, or when im at a stoplight the car misses sometimes, and even more rare it will miss 2-3 times and shut off.. The car will IMMEDIATLY start as soon as I turn the key.

This problem does not happen all the time, as a matter of fact, it didnt happen all weekend until tonight on my way home, it missed a few times, died a few times, then it was fine for the rest of the ride home.

I already replaced the Main Relay in hopes that would fix the problem.

I do NOT believe this is a fuel issue, because of how the car shuts off and starts right back up. It sounds more of an ignition problem.

H-T come help this noob out

 

Have you thought of trying a new cap/rotor button and check the plug gaps?

 

Plug gaps are OK, I just pulled them out and checked about a week ago..

The problem has been happening for about a month now. It actually just started stalling out for like a week and a half though.

Cap/Rotor were replaced less than a month ago.

 

The car also has a bad TPS. Its been bad the whole time ive owned the car and ive never had any problems so I doubt its that. I just havn't gotten around to replacing it.

 

Tps may be the problem, if its bad its not putting in the correct amount of fuel. Could be too much and causing a miss, its hard to tell.

 

Yeah thats true, it's just weird that the TPS would not cause a problem until now.. Oh well, ill start looking for a replacement locally.

 

could be the tune. my car did this when using a map i made. then got it tuned by a pro, and it never did it again.

 

by any chance is your radiator low at all? sometime if you have a blown headgasket when water leaks into your cylinder it will get too much in and cause it to not fire then you're running on 3 cylinders and it will shut off. just tryin to think outside the box for ya. try the tps sensor first though.

As for the head gasket comment, no, its not the head gasket.
