Rough Engine Idle

Postby Vinchenzzi [OP] » May 12 2012, 2:56am

My truck has 80k on it, i just purchased this vehicle and the engine idles a little rough. I was going to give it a tune-up because thats about all i will try and attempt as far as maitenance but was hoping maybe someone may have a better idea what could be causing it. Not sure what other info you may need to help me so Thanks in advance for any help.

i had a similar problem at 86k, i replaced my spark plugs, spark plug wires, and intake manifold gaskets and one or more of those fixed my idle issue, did all 3 at the same time.

Not a bad video, but it could have done without the sound effects.
