” Symptoms ”

Are a lack of power during the day

it gets to the point to where I lose MPH when going up all hills and it takes a 1/4 mile to
get it up to 45 and longer to get it up to 70

it was quick just a month ago also as it reaches normal running temperature that’s when the power starts to lose it bad yet it runs better at
night until it gets warmed up again

I have a 2001 Pontiac Grand Prix SE,3.1 L engine.The wipers only work on high or
off,no low or intermittant.Ive changed out the Combo switch(turn
signal,cruise,and wiper delay) It still does the same thing.I cannot find a
Relay to the wiper system,but ive heard about the Wiper Pulse Module.Do you
think this is the problem ?  Thanks Danny

Gentlemen, have a 1997 Pontiac Grand Prix, 3800V6 engine which begins to overheat while stopped.  Suspect both cooling fans are inoperative.  Have checked main 30 amp fuses which are good.  Can you assist with diagnostics on how to determine if relays and/or cooling fan motors are working or not.

Hi,

i am trying to replace the alternator on my wifes sunfire.  it is a 1997 with the 2.2 engine.i can not find the belt tensioner to save my life.  there is only one idler pully in the engine and it is a thru bolt not a spring loaded tensioner.  the othe pulleys all do something, water, ac, crank steering, alt.  when i remove the idler pulley, it has an allen bolt that appears to attach to the block, is this the tensioner, and if so how do you get a tool in there, because when installed, the pulley is almost flush with the block.  thanks in advance. a cupla pics

1995 Bonneville, AC and heater only blow through the floor vent and defrost vents, not the middle ones.

What might cause my 1998 pontiac trans sport to suddenly be going through more fuel under the same driving conditions and gas quality?  The oil was just changed recently and this has not helped.

Should my air injection pump run all the time when the engine is running and if not, what controls its operation? Will it burn out if it runs all the time?

I am experiencing high RPM’s when I accelerate to 65-70 MPH and the RPM’s remain high unitl I let up off the gas some and then it goes down, but once a accelerate again they go right back up. There is a leak in my exhaust, would this be causing the high RPM’s?

My car started running hot about three weeks ago. Heater would work on and off. Checked water and had oil in it. Replaced intake and head gaskets. Flushed Radiator. Ran fine for day or two. Started running hot again. Heat did not work at all. Changed thermostat. It was stuck. Flushed again. no change, still running hot. Replaced water pump. No change. No oil in water, heat still not working even after new thermostat. Can idle for a while but when accelerated or tr to drive it instantly begins to run hot. Not sure what else to do. Any advice would be greatly appreciated. Thanks
