2009 chevy malibu variable valve timing system problem? It has lost engine power. Won't go faster than 25 mph. Check engine light on. Onstar diagnostics says variable valve timing system issue. Is it covered under powertrain warranty? Easy fix? Common problem?

SOURCE: 2006 chevy malibu.... where is the egr valve

If it's a US car then there is not an egr on the 2.2L engine. I think some of the mexican and oversea's engines had them, but not here in the US.

The first step is to remove all the parts that are in the way of you being able to remove the valve covers. (Ex.: air intake, loose wires etc.) Then you will need to remove your valve covers (using basic tools) and be very careful to not let anything get on your lifters, which your valve covers protect. Once you have the valve covers off compare the new gaskets to make sure they are the right size. Then remove the old gasket and replace with the new one using a high temp gasket sealant (available at any auto parts store) to attach the gasket to the valve covers. Then tighten down snug and check for leaks after replaced.

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.

Hello
Anytime this happens the computer that controls the systems of the car sets a fault code in memory, what are the codes you are getting? without that information it is impossible to even guess the problem. Another issue is this, did the dealer confirm the problem? Another point is that if you attempt any repairs you will void the warranty, and trust me they will do it. What would this 35 year dealer tech advise? Contact the dealer and request a GM factory service engineer get involved in the repair, then you WILL get the problem resolved. You can also call GM, the number is in the owners manual.
