I'm fighting with the idle on my '85
Above 185F start waving , then die.
No error code
What I already did:
- Replaced all injectors
- Checked all vacuums hoses, no leak
- Checked EGR
- Checked fuel pressure
- Checked Air Divert solenoid
- New IAC
- Adjusted TPS
- New PCV
- New MAF
- Logged lived data with WINALDL , seems all good
When surging and I give extra air by removing the vacuum host what comes from the canister and goest to the intake, that solve the issue. But this is not a nice solution, but indicate the engine needs more air.
On MAF connector I have 4,6v on the pink and 12 on the green. The looks OK.
I did the burnoff module diagnostic, and at the first step I got 4.5V on the terminal E - should be above 10V.
Do I need to replace the burnoff module, can that cause the idle problem?
Thanks - I have this issue long time ago, already read all related topics
O2 is new , working well based on live data from ECM.
EGR has not been replaced, checked with vacuum pump, it keeps the vacuum , I believe it work .
Idle problem, burnoff module
