SOURCE: Transmission Problem

Its flood a tranny sensor causing a circuit fault, rain water conducts electricity. Locate this/these sensors and coat them with a sealing agent, your local auto parts store will have the stuff you need. No water, no short.

SOURCE: 1995 Chevy K1500 4.3L V6. Engine has inconsistant idle

Have you changed the fuel pump yet?I had the same exact problem.I replaced my fuel pump with an AUTOZONE PIECE OF JUNK fuel pump.That pump lasted almost 2 days.The second day i had it the truck didnt want to start but it did and it ran like ****,and when i put it in gear it ran as long as I didnt touch that gas pedal.You could go get a fuel pressure test or just replace it,your call.You might want to check your filter too but im sure its the pump.Good luck

SOURCE: 95 Chevy C-1500 runs rough at idle and during accelleration

Check the vacuum line to the fuel pressure regulator and check to see if the fuel pressure regulator has gone bad. Give the throttle body a good cleaning and the injectors too. Do not use carb cleaner, it's to corrosive for the gaskets used in the throttle body. The other thing too that would cause this is a stuck or bad EGR valve, Try cleaning the EGR valve too since your cleaning the throttle body. Good luck and keep me posted.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 (1996 and newer) or a OBD1 (1995 and older) fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

91 CHEVY LUMINA IS IDLING VERY HIGH,AND CAT IS TURNING ORANGE,THATS HOW HOT IT GETS


Check for a stuck open EGR valve,it will have to be removed to be checked.Or you have a large vacuum leak,either one will increase idle and fuel causing hot cat and high idle.

Check your Ignition timing before anything
check your plugs see what color they are
red or orange means carb is to lean , black
or oil means to rich then you can go from there
and set mixture screws on carb , let me no how you make out .

1991 Isuzu 4X4 Pickup 3.1 V6 won't warm start plus shudder in low


Your flywheel sound like it has hot spots on it, making the clutch chatter. You might need to pull the flywheel off and get it re-surface. This is like turning your rotor, or brake drum. If you pull the flywheel, you will see discolor spots on your flywheel. This is called hot spots, and will make the clutch slip.

On the other problem, have you changed to fuel filter and fuel pump. It almost sound like your running out of fuel????
