the car is a 94 civic cx with a 97 b20 with everything converted to obd1. the car starts up but when it was time to drive, it drives good just driving normal but once I give it gas, the motor jus boggs and doesnt want to go forward. if anyone one knoes what the problem might be, please help. the motor was a running motor, it came out of my ek. thanks

 

IF you smell gas ....you might be running rich....do you have a check engine light?

 

nah, he's actually running lean...what ecu you running?

no MIL?

 

ive tried a stock ls ecu, a stock dx, and a chipped ls ecu and it does the same. the motor is stock with just header and intake. its the exact setup that I had in my ek. it ran perfect but I sold it and swapped it into an eg and now its like ****. only CEL is for IAT which was same code I had for the ek. but there was no problem at all..

ohhhh no,........

you plugged the wrong plug into the iac....the plug going to the iac is a green and a red wire .....make sure you plugged that in right first..

 

if its still throwing the code, remove the iac, more than likely its burnt check it out...the ground on the iac runs to the ecu and is in the same curcuit ground for the o2 sensor=thus air fuel mixture ...

 

if it helps im using a obd1 ls wire harness and also what I forgot to mention was when I got the wire harness from a friend, the distributor and o2 sensor plug was cut off so I had to rewire the plugs. basicailly I found a cut up wire harness from another friend and just took the o2 and distributor plug and just color matched it. I knoe I couldnt have messed up on that, matching colors isnt too hard

 

did you check the iac wires like i asked?

this would def cause your problem, being that the o2 sensor is in the same circuit ground with the iac....

 

so the iacv sensor plug is the green/red one right? what color is the iat and egr I believe sensor plug?? thanks
