    Quaderjunk is what some refer to as the TPI injecter set up on your caprice.. and this problem could be almost anything.. I would check your ground wire, maybe even the pick up coil is starting to get weak..

Usually a problem with a dirty throttle body or a faulty idle air control valve. The computer controls idle speed by regulating how much air enters the intake thru the valve.

The car needs to be scanned. It is free at Autozone, Oreilys, and Advance autoparts. Get the Code number for the bad part. The clerks can tell you what is wrong.

My caprice starts and runs for a while then after about 45 mins of driving it hesitates to pull off and idles up and down. then if i cut it off, i wont start unless it sits for about a hour or so... PLEASE...


Sounds like you need to check your converter. May be trying to stop up. Eventualy you may smell fumes. Take to a muffler shop and have it checked. It's hard to say this is what it is but it's where i would start. You may have got'en some bad gas somewhere. Good Luck to you.

A bad thing about this car their distributor is in front of the engine catching all the road slop. You may need to replace this. Since you replaced the fuel filter have you replaced the air also? Did you try a bottle of fuel injector cleaner? Good luck and I hope my suggestions helps

I have a 1992 chevy caprice.when car sits overnight i go to start it and it cranks over probably 7or 8 times then starts and runs good.i had a 1977 chevy with a carburator and it fired up in about 1.5 to 2...


No this is not normal at all and you have a problem. FI engines should start immediately and run great without any hesitation. It can be a partially clogged fuel filter. Replace the fuel filter ASAP. It can also be a weak fuel pump or defective fuel pressure regulator especially on a 18 year old car. Fuel pump is located on top and inside the fuel tank. The tank must be removed to replace the fuel pump. After replacing the fuel filter and fuel pressure test will tell you if the pump is going bad.

Hesitates when going 55mph


How does it perform acceleration wise up to 55 mph? If good, then I'd have exhaust checked for restriction as well, as in plugged catalytic converter.
