ok my car is messin up agin.misfire number 4 cyl.1996 grand prix 3100.take off is nothin but shakin ocatioally stalls studders in accel and while just driving there is alot of fuel usage especial if its not premium gas.also a bad fuel odor in exhaust.where the egr unbolts i shot sum throttle body cleaner in the plenum side and it just filled the hole while was running so i ran a pipe cleaner thru there after a couple passes it finally got vaccum could this clogged plenum cause theese problems or could it be somthing else? thank you

There are many things that can cause your symptoms, including a blocked EGR passage.

ok i cleaned out my intake agin now there is very strong vaccum so much its back to pulling down on the egr.but is still very rough but when i take the egr off it runs very smooth.havent driven it but just sitting with it off everything evens out.it runs quite and very smooth.but when i put the egr back on its rough agin.my egr is bad but has been before this problem came along.so if the egr is the problem is there any way to get around it for now?if it isnt the problem what could it be thanks
