2 had gas in them by the way. I will move them to the other side of the motor Drivers side. That bank was clean no issues. I think they are leaking. I will work on that and see what happens.

Very good I will check on that. TYTY

So here is an up date. I put in all new wires and plugs and did a compression test. The Compression test look good all between 135 and 145 so that ruled out anything broke in the engine. But what I did find out is one of the plug had gas in it. I could dump the clean gas out of the plug on to my table. I repeated that process twice and both times when I took the plug out it had gas in it. Question could a dirty fuel injector cause that ? I also put a spark plug tester on the wire and started the truck and I had good spark coming off the test wire, I saw the light coming on and off. I am thinking dirty fuel injectors. Her is a video on you tube of me stepping on the gas and the truck smoking. The smoke has condensation dripping out the tail pipe and a very bad smell of gas. https://youtu.be/Am_GreAFMsU Please Help. TY Regards Wolfie

Very good thank you

Very good ty I was thinking O2 myself. Where is the MAC and IAC located and do you have a pic for me to look at on those valves.

Hi Everyone I did a compression test on my 2002 gmc sierra It has a SL - V8 - 5.3L 5328cc 325ci I am looking for the compression spec and can't seem to find it on the web I am getting about 135 to 145 on each cylinder. Not sure what the spec is. Any help would be great. The engine is running like crap so I am doing new plugs and wires and a compression test to start with. When at idle the tail pipe has a very strong smell of gas. When I back up the truck bucks. After a few minutes when the truck warms up and I step on the gas there is a lot of smoke out the tail pipe. Rough starting as well. Those are the issues I am having. Her is a link address on you tube https://youtu.be/xkrSI28xHBc This is a video I made of the truck on rough idle. Thank you for any help.
