This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

Where is the egr on a trail blazer 2002 4.2 l


I can't find any listing showing that this 4.2 6 cylinder engine uses an EGR valve, and I have read chevy owners saying the same thing about this engine. It does have a block off plate, but no valve mounted. If had one it would be bolted to the top passenger side of the engine

2002 Chevy Trailblazer 6 cyclinder engine (112,000 miles to date) choking up at idle (not stalling, yet), smell of surpur at tailpipe exhaust, computer code P1345 for the camshaft and chankshaft sensor...


It sounds like your EGR valve needs to be replaced. You can go to any auto parts store and get one. Try replacing spark plugs and plug wires also. If the timing was off it would pick up speed slowly and would vibrate really bad at idle. When you go to accelerate if it doesn't accelerate normally it may be the timing but i highly dought it. Try plugs and wires first. then the EGR valve.

Chevy 2002 Malibu ERG valve


Symptoms of a bad EGR valve are usually stumbling idle or the engine stalling when the car is warm (normal operating temperature). Find the EGR valve and locate the vacuum line attached to it. Start the engine cold and wait for it to warm up. When the engine starts to stumble, pull off the vacuum line. If the EGR is bad, the engine idle will stabilize and no longer stumble.
