Rough idle

[zx6-guy29]

'96 Sport, 5 speed, OHV V6. It is idling rough when engine is warm, but no CEL and no stored codes. New plugs, wires. (It did improve a little after that) Did a test on the MAF and it is fine. Otherwise runs like a champ and accelerates smoothly and gas mileage is where it should be. Any ideas? IAC or TPS maybe?

Based on your description, I would strongly consider IAC problems.

You can attempt to clean it, but more than likely you will need to replace the IAC.

Good luck ........

Also run a can of Sea Foam throught it.

Sea Foam? Never heard of it, but of course I have been living outside the US for several years now. Is this an addative?

thanks! I will replace the IAC and run a can of this through it (that is of course if I can find it here in Germany) but the IAC will hopefully make a difference
