motor: b16a2
car: 96 dx hatch
ecu: chipped p28 with conversion harness
problem: car will not rev past 3k or so.

Initially, the car was in limp mode or so I thought. Vtec pressure switch wire was in the wrong place. Car started fine but had a CEL #22, would not rev past 3k, idle was flucturating a little and was dumping a lot of fuel. I fixed the wire and reset the ecu. Upon restarting, the CEL went away and car was starting/idling fine. I also put a set of fresh plugs in the car as the others were fouled out due to all the fuel that was being dumped. Took it down the street for a test run and the car revved up as it should. When returning though, it started acting up again. Same problem- can't rev it up, just bogging at about 3k.

Figuring it might be the tps sensor, I swapped out the throttle body with a known working one and upon starting the car its idling like **** and will not rev past 3k or so still. In addition to this, I have swapped out the distributor and ecu with known working ones. what else could it be? Timing is perfect. However, the new plugs i put in are fouled out once again from too much fuel. any ideas? thanks!

 

What engine harness did you use?

Did you do the IACV fix?

A14 to A12?

Not sure if you need to do it since you used the conversion harness but I'm thinking you still need to.

 

i used the stock dx harness. yes, the iacv fix was performed.
