Ok so I have a 93 Del sol that had the stock d15b7 and i pulled it and put in a JDM D16A with is just a Z6. The engine i pulled myself from a buddy's car when we put in his B18, so i know the engine runs. We are running the same distributor, wiring harness and ecu(p28) that was in his car which is a 93 coupe. Compression is good, were getting power to everything, and we ran all the wires for the vtec(delsols are prewired) from the sensors to the plug at shock tower. The car starts fine, idles great, but hits fuel shut off at 2800. and im getting cel codes for tps, iac valve, map sensor. I tried 2 stock tps and a blox didnt fix it. 2 different iac both cleaned didnt fix. multiple map sensors one came right off running car and still wont fix. also tried wiring in a 4wire o2 and didnt fix it. I am running out of things to check. if anyone has any other ideas or has had any of these issues please respond. Thanks.

 

mixed up sensor plugs??

 

No checked them all with wiring schematic and traced them all back to ecu to ensure they were pinned right.

 

Look pinout tps again ... may be need to change the 1 and 3 wires on a plug tps
