Hey guys and gals.
I have a 1989 Bronco. I got it at an auction so i don't know the history behind it. It has a surging idle whether its cold or warm. sometimes it will will go away then come right back. someone had replaced the exuaust manifolds with long tube headers. I removed them and put shorty headers with basami Y pipe and added the O2 sensor as it had been removed. I have cleaned the throttle body, replaced the TPS, IAC, Distributor/plugs/wires/coil, MAP sensor, high pressure fuel pump, fuel filter, fuel pressure regulator. I've taken out the computer and inspected it for damage or bad capacitors and even swapped in a different computer with no luck. The only other thing that i can think of trying is checking all the grounds making sure they have good connections. I am at a loss with the idle. Please help!!! |
