    Well i drove to south jersey with my truck the other night to pick a a used honda foreman atv and on my way there climbing this little hill i noticed my truck was missing. I do have a bunch of manifold bolts broken but it doesnt leak too bad when warm. Wouldnt you think if it was that it would be worse when cold? Well the truck has 133,000 miles with original plugs and wires. You think this could be the cause? Do you replace just plugs or do both? The plug wires are soo short and i got a price for delco ones at my local parts place and they are 111 dollars. I find that rediculous. I did install a k&n panel filter about 1.5 months ago. I have heard of them causing oil on MAF sensor. You think thats the problem? I have a maf sensor cleaner is it worth a try? Keep in mind this happened about 10 maybe 15 minutes after i got gas in new jersey since its soo cheap there. Seems to happen on slight inclines

    did not use the MAF cleaner. it will damage your MAF. the broken manifold bolts might cause some of the issue but the plugs and wires are probably going to be it. but definitely get those manifold bolts fixed. on those engines plugs and wires are due to be changed at 100k miles. its a little bit past

    Yea... the first thing that came to my head was plugs and wires. I am goiing to do the plugs, wires, manifolds and bolts, and lastly the fuel filter. Anybody have any hints for this job. Its going to be a long weekend. ahhhhh

    I recommend replacing parts with acdelco and you shouldn't have a problem.Make sure you check the gap on the spark plugs before installing them.

    GM recommends at 100,000 miles: oil change,oil filter,atf fluid and filter change,transfer case fluid change,and spark plugs.
