Your long term fuel trim is pretty low
Have you cleared the ECM every time you troubleshoot?
Yes, no codes are in the system, unplugged the orange wire by battery
Idle car, reach under the EGR and squeeze the diaphram, car should bog
Yes, just checked, bogs bad
But with your BLM at 115 to 120 your pulling alot more fuel then you should, doesnt point towards a vac leak but a spark issue perhaps. but id still bet on TPS or maybe coolent sensor , whats coolent reading? Have a 160deg thermostat, and with regular driving stays 160-170. Car has a new water pump, radiator, etc etc etc.
whats the cross counts on SM? are they cycling good to 255 or lazy?
cc- starts at 0-10, goes up by 30 every second, all the way up to 252 was highest I saw in 3 cycles. I must admit complete ignorance on the use/behavior of cc on my SM. I was always concerned with KR and O2, and TPS and MPH!
This is awesome, what should I try next?
Should I 'reset' the TPS, or try a new sensor altogether? The TPS seems very quick and smooth on the SM.
