More info is needed for even a basic diagnoses; over 40K miles, on a fuel injected/throttle body, it could be a fuel filter or clogged jets. More specific information/specific details will lead to more definitive answers.

    over 40k on the engine and someone recently changed inj or replaced seals to try and solve this problem never did get a straight answer what else do you need to know

    One suggestion regarding fuel filter is to correctly install a new one - when it was turned around, it may have backwashed the impurities into the throttle body/injectors plus use a good fuel conditioner/cleaner like Lucas fuel system cleaner. With so many vehicles being controlled electronicall, it could be one of the sensors- if you have access to a CAN OBD reader that plugs in below your steering colum, under the dash, it will give you a readout-be very careful if you are not familuar with the tool-read the directions or have somone with tool experience help you; there are "mass airflow sensors, throttle body/injector sensors, etc...Keep me posted...

    Sorry for the typos - for some reason, I cannot see some of the things I am typing until my data is posted...

  • Gsquare Jan 04, 2013

    One other thing - try a different fuel station and run a tank of premium with the Lucas cleaner; water and contaminates are not uncommon in some fuel stations; I use to have a truck stop and shortly after my purchase, I learned how much water is in the tanks after I paid for a couple of dozen vehicles to have their tans drained and fuel systems cleaned.

SOURCE: Rough idle 1994 chevy pick up k1500 4x4

I had a 96 GMC 1500 with a 5.7 ltr. It would idle rough, especially on start up. After replacing everything under the sun, it turned out the ECM (computer) was shot. I found a used one and plugged it in and it ran fine. I think I paid 50 bucks or so for it. If you know someone with a truck like yours, plug theirs in and see if it fixes it.

SOURCE: 1992 pontiac grand am no acceleration, a rough idle (engine miss)

Does it have the 2.3l Quad 4 engine? If so replace the plastic piece that the coils go into, they go bad and leak spark to the cam towers and then you get a nice one or multiple cylinder misfire.

SOURCE: eingine idles rough, sputters and misses on

My recomendations would be to check your plugs and wires for damage.Check the fuel pressure to the fuel rails for proper pressure.This should be done by your local shop.If the pressure is low it could possibly a fuel pressure regulator,clogged filter,fuel pump going bad or bad injectors.Also inspect your ignition timing and components in the ignition system for proper operation.All of these things are tied into the computer to assure proper operation.Allways start with the plugs and wires if they have alot of miles on them and then the fuel delivery system.I hope some of this info will help you narrow down your search for this problem.

Engine missing is a vast subject and calls for number of things to examine. What are the problem symptoms? Is it concerned with one or more of the following?
- Rough idle, stalls or misses.
- Engine hesitates/ poor acceleration.
- Engine diesels (runs after ignition switch is turned off).
- Muffler explosion (after fire) on deceleration only.
- Engine backfires.
- Engine rattles at idle speed only.
- Engine rattles at all speeds.
Please mention if there is some other symptom.
Thanks.

If you had no previous problems then it is something you have missed in the installation of the radiator. Check for pinched wiring missed earth wires water lever sensor etc
