Well it hasn't happened to me yet. Well not with this truck. But I know very well how problematic these little buggers are on GM's. They were a problem with Grand ams also as I had two of those also.

Well with my Jimmy, it's been getting worse. But what has been happening is it has had trouble with quick starts. Like sitting at a light and needing to go quick, or to pull out from a stop into traffic from a side street. lately what would happen is if I stomped on it it would hesitate. And lately it was getting to the point that it would totally die, or completely bog down, and it wouldn't let up until I let off the gas and then stomped on it again. If I tried to take off and it would hesitate it would continually bog down until I let off the gas. Really annoying. And I was trying to figure out what it was. Well last week the SES light came on. So I hooked up the ODBII meter and checked the codes. Sure enough MAP sensor error. So I just went to my local pick a part and found 1. 1 out of 4 trucks that would have had it. Got home, swapped it out and runs good again. It always RAN fine but now I can take off from stop without it bogging down, or all out stalling.
