there is a relay on the driver side firewall of a 89 trans am tpi with 5 wires going into it,RED BLACK/WHITE PINK/WHITE BLUE ORANGE. what is that relay for?


Relay get warm when its plugged in and car has a slow throttle response, like it drops about 100-200 rpms before accelerating, its got new MAF, ESC, IACV, ROTOR, SPARK PLUG WIRES, SPARK PLUGS, DIZZY CAP, DIZZY MODULE, COIL, TPS was adjusted and its within specs. WATER TEMP SENSOR,

When i unplug it it runs way better with a very fast throttle response but i get a ses MAF HIGH and ESC FAILURE.

Please help me identify this sensor.

Its a 350 with '165 ecm, chipped by tpichips, 24# injectors, fuel pressure ~45, LT1 intake conversion.

Sounds like the MAF relay. Plug the relay back in and unplug the MAF connector. See if it acts the same way. If so, then it is the MAF sensor relay.

mmhmm, didnt think of that..

I hope its not a wiring problem , i would hate having to go through all the wires trying find the problem
