I have a 94 civic.I have replaced the tps, plugs, wires, and fuel filter. Its like a little miss and when it is cold it misses a little worse. But when I give it gas and drive it she runs fine. When I got it she was throwing two codes (tbs and fuel supply). But when I fixed tps it has no codes now. Please help thanks.

 

Did you calibrate the tps? Also you can clean your iacv and fitv.

 

clean/fix ALL vehicle grounds.. check the ohms of the spark plug wires..

 

As said above.... Calibrate TPS and check grounds. Also which plugs did you use? OE type? Some singles are known to act up with a/m plugs in em.. also check timing for what its worth, since its an easy task.

 

ya i got the throttle body off a b18 four door teg youll dont think i have loss of compression in one of the cylinders

 

plugs are ngk what she calls for

 

The only way to know for sure if its compression is to just do a compression test. Its very easy.

 

have you checked the tps yet? Calibration?
