Actually no I have not is located under the upper intake too because I do not even see it any where ? But if I can find it I will deff. clean it

 

The EGR valve is on the front of the intake between the alternator and the A/C compressor. It is about the size of a soda can.

 

OK cleaned the EGR still have the problem. Now here is a question after changing the spark plugs I did some research last night and the original factory plugs have a heat range of 2 and the plugs in it now have a heat range of 5, so could this be a problem or am I just beating around the bush??

 

What plugs (brand & part number) were in there and what did you install?

 

Sorry the plugs that were in the engine were the factory plugs AC 41-932 according to GM the heat range on these plugs are 2, now when I put the tune up on it the plugs put in it were Bosch plugs with a heat range of 5 so could the difference in the heat ranges of plugs make my engine miss and stumble?

 

Well, we have definitely had members have problems with Bosch plugs in their engine. I recommend staying with the AC/Delco factory plugs.

 

41993 (replaces 41-932) is the stock heat range for the engine. Any reference to a + or - heat range that you may have found is based off of a different stock engine requirement. Without any specifics on the Bosch (*shudder*) plugs, I cannot comment on them. But why would you be messing with heat ranges???

 

Sorry for the confusion with the plugs I didn't intentionally change the heat range it's what they gave me @autozone. However I do belive I found my problem I unplugged the MAF and drove it and the problem went away. So I guess when I save up enough money I will go and buy a new MAF sorry for so much run around guys but THANK YOU guys for all your help and input it is greatly appriciated.

 

Kyle, If you won't comment on Bosch plugs, other than a shudder... I will. I really only have one thing to say about them, they never misfire if you don't install them.
