Did you replace with the correct part? I thought the camshaft acutator solenoid was a "dealer" only, meaning normal autopsrts stores do not Carry it. If u still have the old sensor throw it in and see if it clears up your issues.
If you have the OEM GM solenoid or Delphi brand solenoid, there shouldn't be any need to change it again. I would just recommend taking a trip to the dealer and have the VCM/PCM reprogrammed with the latest software and then they'll have to perform a crankshaft variation relearn procedure afterwards to setup the VVT correlation. Also if you haven't already, you may want to clean the throttle body and MAF sensor.I changed mine about two months ago,just last week I started getting a rough idle at stop lights,maybe this needs to be changed again.
Are you sure it's the VVT solenoid you replaced because I've yet to see one manufactured by AC Delco?It's a ac delco,I cleaned the throttle body and maf yesterday.
Awesome!!!Well it worked! Replaced with GM part from the dealer and voila no CEL :th_woot: and it actually runs and drives better than before I even started this whole thing lol! Just looking at the GM part you can tell its higher quality, it has wire wrapped around the screens (to prevent them from coming off and disintegrating) and came in an oil lubed packaging. I think I'll stick with OEM parts only from now on when it comes to performance parts. Thanks for the help guys!
When searching for new solenoid be sure it says Genuine GM or OEM because a lot of sellers list the same oem part number and will send you an aftermarket item.After looking on line,I found the seller that I bought my first
one from,the part number listed is the same that you posted,but received the part number that I listed above.I looked for the part number and it shows no listings,hmmm now I am lost.
