Will i hooked a multi-meter to cigarette socket to check my votages. Last night it was doing the low rpm thing(see below). As the rpm would drop to 500 or so the meter readings would drop from a steady 13.8ish to 12.xx. On anther note i was doing some runs with DM. And i was getting about 16 KR @ 19 psi. So i cut the boost to 17psi and i was still getting 6*KR. So i think i just need to bring it down to 15. Are these 2 different problems. What could be causing the rpms to drop like so?
Also i haven't thrown any CE lights since the first time.
From Previous thread:
i noticed yesterday when the truck was idiling for 10 min or so, the idle rpm would drop to around 500 and it would be real rough then rise back to about 1000 and the CE light would flash. then when it was time to put it in reverse the motor would stall. after backing up and putting it in drive it stalled about 2 more times. again flashing the CE light when the rpms got real low. it is also sputtering pretty bad on part throttle just driving aroung town. if i am going thru a parking lot or something maybe about every 4 times i touch the gas peddle the motor will rise in rpms to about 1500-2000 then it will just sputter and not accelerate about 3 seconds later it will be fine. I haven't gotten DM on it yet but i know this is going to be harder than a WOT problem. This has been going on for 2 days the first day not as bad but when it thru the CE light it stayed solid, until yesterday. fuel press is good, base of 50 and rises with boost. At no point was the CE light flashing continously. It would just do a quick one time flash as the rpms met the bottom point.
