- Allready been through 2 tanks of gas
- Engine still gets spark when this behavior happens and will run on starting fluid
- Cleaned idle control valve and throttle body (no idle issues when it does deside to run normal)
- When it runs right it has plenty of power and zoom zoom's no need to test compression

can the temp sensor cause these issues? even if it was bad i would think it would just pull a code and put computer into limp mode at the lease or make it run rich or lean.

egr passage is clogged so its time for a plenum cleaning. when its off all the injector resistances are geting checked to elimate that issue.
