Question about 1996 Chevrolet Blazer

1 Answer

Loud tapping in idle or lifting off the gas pedal (not as bad)

This didn't occur until I "hot rodded" the 2.2 liter  Chevy Cavalier  with a 127,000 miles on it on two successive trips a couple hours apart.  I actually thought the problem was the belt tensioner vibrating onto the pulley above it, but replacement proved not to be the case, unless the new part is just as bad. I searched internet all day and found many possibilities,  but I've got to believe that knowing what occured before this became an issue has got to narrow the choices.

    By "hot rodding" I mean I  reached 100 mph for about 3 seconds- then drove 20 minutes or so in the 80- 90 range . Got home- took nap. An hour later  I took a long trip again around 30 minutes at 80 or so.  I arrived at destination.  I didn't notice the noise until I started up to leave the place. I don't normally drive that fast.

Since its a loud tapping when you at idle & lifting off the gas petal, (ie constant exc for acceleration) then it's probably a lifter, instead of a rod bearing. Way to check, of course, is to use a piece of cut off hose & listen at the top of the engine, and at the oil pan. Just don't get the hose caught in any belts or fan blade. Listening should easily solve your problem. Rick

Sounds like fuel starvation. 1) change fuel filter. 2) change fuel pump. GM pumps don't hold up to water in the tank (methanol fuel) very well. Its a 2003 so its probably time. Never replace as many parts as you have, without first performing an OBDII scan of the stored fault history, to avoid buying parts you don't need

No power, jerking bad 1998 cavalier

Possible dirty fuel filter. I'd start there first, as it's the cheapest route, and quite possibly replacing the filter will solve your problem.
