Goodafternoon, my hummer h3 idles, shakes and trembles when its in park and while driving. make a huge sound while turning it on and takes forever to turn on as well. Traction failed light turns on
Mechanic's Assistant: Just to clarify, what are the exact lights you're talking about?
Check engine light and the Stab. Sys traction failed
Mechanic's Assistant: What year is your H3?
2008
Mechanic's Assistant: Are you fixing your H3 yourself? What have you tried so far?
I had a mechanic come to check it and he said it was the camshaft and crank shaft so i had him replace them , he also said the spark plugs were mad and that they has oil in them which he said wasnt an issue, still had him replace the spark plugs just in case. he made my h3 get worse than it already was
Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you?
No! thank you

He may have gotten the spark plug wires crossed causing the misfire.
As far as the warning lights go, get the trouble codes retrieved from the body control module and any other module for that matter to see if perhaps the computer has already found a problem and has set a code in memory for it or them.

I assume you meant he changed the camshaft and crankshaft position sensors?

When you went to purchase these parts did you ask for sensors or the actual shafts?
Why didn't he just find new screws?
