You need to replace the pick-up magnet for the cam sensor. It is pushed into the cam gear. You have to remove the timing chain to install it.

Replaced plugs, had a tune up, replaced air filter but still idles high in p&n drive is at around 1000 p&n runs close to 2000. it also runs bad... shakes and if in drive and stopped for to long...


The first thing I would have checked is the TPS, ( throttle position sensor ), this is usually the cause of a high idle.

As far as running bad and fake stalling or stalling, there are 2 very common things that can cause that.

1. MAF, ( mass air flow ), sensor. If this is faulty you will have issues like, bad idle, loss of power when accelerating, poor gas mileage, fake stalling and stalling, eventually your engine will not start.

2. Oxygen sensors. Faulty oxygen sensors can cause very similar symptoms as the MAF.

I hope this helps you.

Hi, you may have a torn brake booster diaphram. Try disconnecting the brake booster and plugging the hose with a rag. Don't drive it without the booster, but set the parking brake and see how it runs in the driveway. If this clears up the problem, replace the booster.

Check your catalytic converter, good chance that it has broken apart and is blocking exhaust flow. Common Chevy 4.3L Issue.

2000 Monte Carlo SS- Stalls after running 5-15 minutes


Check the plug on the MAF.Wiggle it while its running......see if it stalls or jerks.
Or.......replace the MAF if the plug/wire connections are good to it.
The other 2 codes will not stall the engine.

Remember.....all cars run on used parts.
A good used MAF can be had a lot cheaper than new.

I'd check for vacuum leaks next. use a spray can of intake or brake cleaner. spray around vacuum lines, manifold gaskets etc. if the rpm increases you found a leak.

Sounds like you have a c/v joint beginning to go bad...Could be wrong.... but, I'm not there to test it! Look underneath and see if any c/v boots are torn... that will be your first clue!!
