If it's backfiring after changing plugs and wires you probably cross-connected a couple of the plug wires. You will need to put the plug wires into the right distributor socket. To do that, find the firing order and use a little deductive logic. didn't cross wires, did wires one at the time so not to make that mistake and too noticed just now that the fuel pump does make the hum noise and there is fluid in the tailpipe along with lots of black build-up...
if it only backfires when shutting off, usually this means its getting to much gas!! if it backfires will running adjust carburater.
the seat on the exhaust valve is dirty so the valve does not seal it.... not sure how to clean it
It may just need a tuneup of Plugs and wires....Or your coil pack maybe Failing.
Try running a sand cleaner through the pump at the end of each season. Have the sand changed every 2-3 years.
If any car backfires it is usually due to retarded timing, running lean or a problem in the valve train.
running lean can cause your 400ex to backfire ..if it backfires on deceleration its lean ...if it pops on acceleration its running rich.====carb issues
Needs a tune up? Bad timing?
No, I recommend go to a mechanic, chances are your firing order is out or running bit to much fuel
I searched the internet and found Running time: 07:47.
Hey E==The running lights have a module which may be bad. Good luckJoe
it could be of running it with out oil.
Remove the air filter, and while the engine is running spray the cleaner into the carb directly, being careful not to stall.
If it backfires after you shut it off then it is probably running too rich. Any unburned gas the that is exhausted out and into the muffler will explode with a backfire. With a 1990 model you won't have the anti-backfire solenoid on the bottom of the carb like the newer ones have. If it backfires while it is running it might be out of time. Check the keyway between the crank and flywheel to make sure it is not partially sheared.
Daphne was running from Apollo, and she was running out of breath. She prayed to her father and he changed her into a laurel tree. Thus, why we see Apollo with a laurel crown.
the iat sensor is located on the tube running from the air cleaner the sensor has a wire connector running to it
You can lose about 5 pounds a week running 24 miles. This also depends if you have changed your diet and what you have changed your diet to.
By keeping vehicles running their best for cleaner emissions.
Rinse it very well under running water.
i think the computer need to be reprogram
Aerosol throttle body cleaner, sprayed directly in to TB while not running. Only recently have they began labeling it TB cleaner not carb cleaner but it's the same solvent. Use copious amounts
If it is running after the engine is shut off, the relay has failed. It is bolted to the frame under the air cleaner.
No. It should be OK.
because it sucks!
Are you just trying to start the engine, or is it already running? If it is running it sounds like the power steering pump is bad.
