    Thanks for your help guys. All i had to do was buy a new battery. What is weird is that i had taken my battery and alternator to get tested at the auto store and they said they were fine.

    I thought my problem was solved but wasnt. My truck keeps turning off at the turns and its getting pretty dangerous. I hardluy drive it now what a waste of truck.

    if your idling in park and turn the wheel all the way (any dir.) does the vehicle stall. if so then you need what is called power steering pressure switch

Your vehicle is supposed to charge at a rate of 14.4 volts. your volts should never be below 13 while running otherwise alternator is probably bad. If the fuel filter has never been changed it too can cause vehicle struggle to accelerate go dead easily because it is struggling to get gas. I had a 99 tahoe that wouldnt shift out of first when fully accelerating until I let off gas. thought at first trans problems but an eight dollar filter fixed it. just remember that your volts should never go below 12 volts when off, especially when running because it takes 12 v to keep engine computer and all electrical on.

The power steering pressurer switch would be a good replcement,but as for the different RPMS at certain times,it may be you have a bad TROTTLE POSITION SENSOR.Your automatic trans.works partly off of that also.You can call ED BOZARTH service dept. and ask for Larry,he will do the best he can over the phone.THE # IS 785-266-5151. GOOD LUCK! CJQUALL

My 95 tahoe has an occasional ticking noise, loss of oil pressure at idle and loss of power


Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.
