Ok... My car is fugged up. It misfires at part throttle from ~2000-4700rpm. Seems like it wants to fire, then it dies, then suddenly past around 4800 (VTEC changeover) it clears up and runs normal. I am throwing CEL 14, but I don't see how this, the IAC, would have anything to do with the car running like this? Anyone experienced similar problems?

Also, could the TPS not being set at the right ohms or whatever cause this? Help me please!

 

The IACV could definately have something to do with it. I would take it off and clean it up really well and see if that helps another thing you could try is to make sure that you dont have any air in your coolant cause that will also cause a bad idle as well.

 

What is the misfire like? Sporatic, or rythmic.... in other words, does it just randomly miss, or does it miss sort of like a rev limiter, in a certain pattern?

 

do youhave any ecu piggybacks? afc or field controller?

 

The misfire is sparatic. I have the stock ECU, no piggybacks. It was throwing CEL 7 and 14, then I messed with the TPS and it just threw code 14, but was still misfiring. Then today I messed with it more, and there is now a rev limiter at 2500 rpm... I am begining to HATE Hondas... Carburators are looking better and better at this point. My "reliable Honda" breaks at least once a week.
