High engine revs

Thanks will try that. Stay blessed.

Hi Kenny, would you happen to know the measurement of the pintle in parked position in the IAC, the to the open is 28mm. But my pintle came of and I refitted I also tried to reset but car still not right. Thanks

Good morning, God is good today we have partial freedom. I reset the IAC and drove around but to run smooth I set timing to 10 degrees advance and the idle problem still high. The only thing I haven't done is vacuum test because I don't have pump. I got an air tire pump will try that. Thanks a million for taking the time to respond to me. Stay blessed.

Hi Kenny,

When I press under the EGR valve (cleaned) the car used to stumble or cut out now it does not do that, no response from engine when pressed. Thanks

Hi Kenny, trust you are well. Thanks for your time to address me. We in S.A. Back to usual life with precautions, my car listed above 5l. TBI, v8 so far this what I done: I replaced the whole TBI unit with a second hand set, new rotor, plugs, wires, cleaned EGR and co2 sensor, MAP sensor, checked no vacuum leaks, timing set at 6% bdc. The spray from injectors evenly both sides, another temperature sensor: here is where we are at : normal temperature idling at15/25k, no missing or hesitation, drive 30 seconds and then backfires through exhaust lots and if throttled then backfires through carburetor, the code 42 says est gnd or open. I don’t know how to fix. Any help will be appreciated thanks God Bless.
