not goin too well.. with the swap we kept the original wiring harness, put in h22a dohc vtec motor, trans and ecu. i wired map and knock sensor, only error now is 7, tps, i tried a new one and still no response when rotating it or unplugging it.. and I wired it directly to ecu.

how does it run? idles ok but hardly accellerates and after ten min of driving, not at all. if i turn it off for a bit I can go another 10 min. error code = 7. does anyone know which ecu this is in the picture and if this could be the problem? it came with the new motor which was 92-96 prelude.

 

I can't tell from looking at the inside but does it have a white sticker on the side with a code? It should be a P13.

The problem you describe doesnt sound like it could come from a bad TPS. I have driven with a wrongly set TPS and no TPS at all and it didnt run anywhere near that bad.

 

something must be totally wrong, i'll have to go to specialist

 

Aren't these the ones where the map and tps can get swapped by mistake?
