2001 CHEVY MALIBU
Q. I have a 2001 Chevy Malibu and the wipers wouldn’t stop moving then they finally stopped and won’t come back on. What do you think?

A. Test for voltage at the wiper motor. If you have 12 volts replace the motor. If not then the switch itself has most likely failed. If you are unable to run these test yourself consider a NAPA Auto Care Center like Parkway Automotive.

2005 Chevy Silverado
Q. Mike:
My husband has a 2005 Chevy Silverado that smokes when you start it. It will only smoke when the truck is started then it stops. We had the valve seals replaced thinking that would remedy the problem but it is still doing it. I just wanted to see what your thought about might be.
Thanks,
A. I’m sure you were close but most likely the valve guides are worn inside the cylinder heads. It will require the heads to be removed.

1997 GMC JIMMY
Q. have a 1997 GMC Jimmy 4WD. 4.3, 6 Cylinder, Automatic 4-spd with roughly 103,000 miles on it. My problem seems to surface every summer time since I’ve owned it and I have had it at a Chevy dealership hooked up to a diag machine to address this specific issue but the diag machine gave me inconclusive results. In fact, one of the head mechanics was able to drive the truck and regenerate the problem but was unsuccessful in pinpointing the issue. Let me also note that a “check engine” light has not came up when this problem surfaces. Up to this point, we have replaced the spark plugs as well as wiring. So here is what the symptoms are: When the outside temperature is at 95 degrees or hotter, the engine will all of the sudden act as if you have taken your foot completely off of the gas pedal and the tac will suddenly decrease and the engine will die. I have found that when it starts to idle down like I described above, letting off of the gas pedal and the re-applying pressure will “revive” it and it will acknowledge the pushing of the gas pedal. Sometimes that will temporally resolve the issue while usually it will do it a series of times, then it will drive fine for a few miles. If I am able to, I will pull the car over, pop the hood and let it cool off for 30 minutes or so the resume driving. This seems to temporally resolve the problem. I am out of ideas so any assistance in identifying the issue will be greatly appreciated!
Respectively,
Brad
A. it sounds like the fuel pump is failing. You should have a fuel pressure test performed. Remember to always replace the fuel filter when you replace the pump.
