I have had this car for alittle over a year now and it has been running pretty rough at idle and when you come to a stop if feels like it tens to shake and sometimes as if its going to shut off. Also I noticed now at a stop my "check gauges" light comes on and my oil pressure gauge is pegged at zero but when driving it goes away and is normal. Another problem I am having is that my volts gauge fluctuates and most of the time its no marks below 14. The last major issue I am concerned with is when I start up the car and shut it off the motor shakes a bit and like I stated previously at idle it does as well, I can feel it through the pedals and the steering wheel.

Get some carb/throttle boy cleaner & an old toothbrush. Hoold open the throttle plate, spray cleaner in it and on the toothbrush, and scrub. After I spray some on a rag then wipe it out. Put it all back together and start it up. Might run rough for a little bit, but it'll straighten out. See if that helps.

Hello, I bought a 2004 Chevrolet Trailblazer and when i test drove vehical all was good, the next day after i purchased vehical it started idling rough at stops and red lights. I took to Mechanic and it was throwing 3 codes which all three pointed to O2 Sensor, took it back to lot where i purchased and they replaced o2 sensor and when i got home it started idling rough again. since then i have figured out it only does it when heat and air is off. any suggestions? also i figured out the the Check Engine light has been disabled, any suggestions on getting this light re-enabled?
Thanks in advance
Thanks in advance
