2006 Chevy Trailblazer ext

Asked by Meli Jul 26, 2018 at 09:13 AM about the 2006 Chevrolet Trailblazer EXT LT 4WD

Question type: Maintenance & Repair

So I'm stumped. My SUV gets warm and every
single traffic light or slow traffic I hit, the oil
pressure gauge drops down to 0, the check gauges
light comes on, and the dash tells me to stop the
engine. I brought it to the shop and they cleaned
the throttle body and replaced the oil sensor. Now
it's still acting this way, just a tad less. My
mechanic told me the next step is to replace the
entire throttle body. UGH He can't figure it out so he
thinks changing that may do it. Any ideas or
anyone experience this and gotten it fixed?

If you already had a mechanic look at it, I'm not sure how I can help? Anything I can suggest, I'm sure your mechanic has already thought about it? It sounds like your engine is trying to stall when you come to a stop, idle too low? I was going to ask, how long since a tune-up and are there any applicable trouble codes? I looked at info for 4.2L engine, you have electronic throttle control, any codes related to that system? Did your mechanic put a scanner on it to look at live engine data?
