Knocking after seafoam

I used seafoam about two weeks ago but did not have engine running I just poured it I to the hose from intake then I tried to start it wouldn't. Until I realized it could possibly hydrolocked so i took all my plugs out and turned the harmonic balance to get out the seafoam that remained. My truck started right up..but is now knocking. Could it be because I still have seafoam in my cylinders? My oil is fine.

Re: 91 GMC 5.0Distributor Question

So, to continue on...stopped to get gas after work (2nd shift) and set the pump to auto fill, ignition key off. Popped hood and pulled dipstick to check oil and saw a spark as the dipstick came out of the tube. Spark was down where the tube contacts the heat tube from the exhaust manifold to the TBI air inlet. Pulled the spark plug wire away from where it contacted the dipstick tube and pulled the dipstick, no spark. Don't know why there would be any power to anything with the key off. Looks like I'll be chasing some wiring and replacing plug wires.

2006 GMC 2500HD brake switch failure

I have already read a couple of the posts on here about this. I am getting plenty of power which I think is my problem. I replaced my alternator thinking that it was sending too much voltage at 19 V to the that battery. The new alternator came with a spec sheet that said it should be putting out 19.6 V. Is there something between the alternator and whatever else to bump down the voltage? I'm getting full 19 V at my taillights. I've been through 14 brake light switches

2004 GMC Envoy P0410 Trouble Code

This trouble code keeps coming up on my Envoy. Reading information about this code points to the pump not coming on as the primary problem. The pump comes on when the ignition switch is turned on so I'm at a loss as to what to do to repair this problem.


Hello there, can someone please tell me why my 2007 Envoy vibrates only when I turn the a/c on? Spark plugs and and air filter has been replaced. Also check engine light is on and the code says that it's the thermostat. Not sure if the thermostat can cause the vibration. But it will be replace in a few days. Thanks
