I just got back my new ecu its chipped to run my larger injectors etc have had the chip on the engine before now and it ran ok. I buckled the old ecu in a crash .

Anyway I did replace the TPS as I broke it when swapping the engine its one of a zc sohc as well so I imagine its the right one bolted on fine etc...

I have read the ideal voltage you should be getting at idle is around .5 volts and 5volts at WOT I have setup the idle for .5volts WOT seems to only go to around 4.4 or so( is this alright can't get it to read any higher not matter what?).

Car still runs like *** extremely rich. Ends up stalling as the rev's decrease barely will rev splutters etc. Could this be a faulty oxygen sensor? I think I accidently spray painted it

Its not throwing a code, I don't think I have any vaccum leaks.

Any ideas?

 

Not sure if the checked the chip to see if it was still ok, will speak to them tomorow.

 

well dude, sounds like i would definetly check out the chip first. usually 02 sensors dont get so screwed up with just spray paint. and if its completely in the bung then you didnt hurt it. what kind of swap did you do? what size are your injectors and what kind of fuel psi are you getting?

Nah I definitely coated the O2 sensor I was spraying hte paint down the throat of my down pipe. I think I am using chrome not sure if the car would start if hte chip was not ok?
