STARTS UP A LITTLE ROUGH FOR FIRST COUPLE MINUTES,HAD MIL LIGHT ON LAST WEEK,WITH CODE PO137,NOW IT'S OFF, BUT GETTING CODE PO507 ONLY,WITH MIL LIGHT OFF,ANY SUGGESTION AS ALWAYS APPRECIATED,,,,,
Just realized my oil pressure @ idle, is only 20.driving it'll go to 40., is that bad, should I worry, what is cause of it, I'm presently getting code PO137 only, it has a rough start, but after three minutes sounds good, any suggestions appreciated as always,
My truck had a rough start to it 2 months ago and I could smell fuel. I took it to Chevy dealership to run diagnostics and found codes P01072 & P01075 stored in the ECM and alcohol content at 74%. They reprogrammed the ECM and reset the alcohol content and it corrected the starting issue, but they said if light came back on it was likely due to fouled spark plug/wires. I drove around 40miles to my office and parked, got back in an hour later and the check engine light was on again. Stayed on for a day or so and went off. It did not come back on again until today after I left the same dealer ship from getting oil changed & tire rotation. I know what the codes are for and the several issues that can cause them, but wanted to check to see if anyone had similar issues and what they had to due to correct it? I would prefer not to spend a lot of money for them to troubleshoot by changing parts. Thanks

n for two to three minutes. Then it goes off till the next start. Sometimes it will flash on and off. The sensor in front of radiator has been replaced twice. What could the problem be.
My new battery is going down overnight! I can charge it up in the mornings and I can hear some kind of little electric motor running on top rear of engine. What do you think this is?
when in high it has a loud clicking sound and seems one of the front wheels is bucking this only happens when I do a sharp turn. If I am driving in two wheel drive no problem.
there is two plugs on right side of throttle body,where intake hose is connected,one on top is the air control,i think, the other one is two inches under it,1999 silverado 1500,4.8,V8 VORTEC,4X4

My 2002 Chevrolet Silverado 1500 extended cab V8 1/2 Ton 4WD with Floor Mounted 4wd shifter, will sometimes stick and not disengage from 4wd back to 2wd. Also makes noise.
Driving on the highway, the RPM's shot up and then I noticed the trans guage was higher than normal. Just had a new engine put in it and all fluids changed and checked.
I know what the part looks like & that it has to do with the gas tank. Cannot find where it is - hopefully I do not have to pull gas tank !
Thanks Tom Mc
