Hello guys,
I have had good luck asking and reading here so after reading as much as I could with no luck I'm gonna ask.
I have a 2002 trailblazer 4.2 periodically I start the truck and wait for the rpms to drop to normal idle (usually 30 seconds to a min) then put into D and give it gas to pull away from curb, the truck seems to fall all over itself with ZERO Power, it struggles to get up to 15-20 mph, if I pull over turn off truck wait a couple min and then star again and it's fine. Today I was on my way home from work and at a stop light it did it again, it wouldn't go above 20 mph, pulled over and turned off truck, waited a few min restarted same thing, tried this about two times and still same issue, went to try and make it home and it would shift finally and shifted thru gears just fine but still had no power. If I would stop and start off in first and manually shift it got up to speed faster but still had issues. I want to say the trans is ok due to the engine and trans does shift smooth. It's almost like the breaks are on and I'm trying to drive with e break on, but I'm not and I jacked up all corners and the wheels move freely.
Any ideas???
