I have a 92 prelude with a h22a swap. Never had problems with it since the swap, about 3 years. I was driving and all of a sudden it started sputtering when I pressed on the gas and then it died. It wont start back up until it is cold. I drove it again and then let it sit in the driveway for about 15 minutes and then it died again. I replaced the spark plugs, spark plug wires, and distributor cap and rotor. I've heard it could be the coil pack, but some say they have never seen the coil pack go bad. Any suggestions would be greatly appreciated.

 

bad solder joint/hairline crack in some circuit board somewhere? i am guessing the heat would cause it to expand enough to cause an open and when it cool down, it would make contact again. Main relay?

 

I changed the coil pack. It still dies. Maybe ignition module?

 

with all of the money that you randomly spent on ignition parts, you could've hired a mechanic to diagnose your problem. check for spark and fuel after it is warmed up and dies. Could also be compression.

any cels?

 

No cels. And all that was about $100.

 

then check for spark and fuel after its warmed.

 

Did you resolder the points on the main relay? This has been a problem since the 80s. Either change the main relay or resolder the contacts on the circuit board, search main relay fix or something of that nature and you'll find tons of info on it.

 

Maybe the IACV. might be clogged somehow. Its suppose to keep the RPMS high until warm...

 

By his description it didn't seem like it was happening that quickly, which would rule out IACV or MAP
