I brought the van to a dealer (Noonan Pontiac) in Sterling heights MI. Dealer checks out the SES light first, and reports to me that:
"Well, it says Crank sensor bad, Cam pos sensor bad, Evap vent solenoid bad, and PCM shorting out. Plus, there's obviously a leak in the intake manifold. We didn't even check on the tach sensor problem yet.
Evan solenoid - $210
PCM - $520
Intake manoifold - $1200
I'd suggest that we cut your losses. Why don't you just come in for a trade in?"
I am insulted! Rather than fix the problems, they want me to trade it in! I had the intake manifold replaced 30k ago (at the same dealer), and they want me to replace it again!?!
Dealer also says PCM is a "dealer only" fix, since it "needs to be reprogrammed while it is on the vehicle, and only dealers have the ODBII programming equipment to do it". Sounds fishy to me.
Just FYI.
