Why is your vw backfiring?
If a car backfires, the fuel mixture is incorrect. I believe it's too lean. Also, timing could be off. Try increasing the fuel mixture with the jets on the carburetor. You may want to reference your VW shop manual for which one to use. If that doesn't solve the problem, then have a garage time the vehicle to make sure pre-ignition isn't happening.
What can cause a 1995 caprice to backfire?
A flat camshaft could cause this if you have already ruled out wrong wire order and any other ignition problems. Each factor would have to be checked in order to determine the real problem.
What is causing your 2003 Mitsubishi Montero to backfire?
A backfire is when the ignition of fuel doesn't take place in the ignition/combustion chamber, it(a backfire) can take place in the intake or exhaust. It can be caused by a fuel to air ratio not being correct, also if the timing of the spark is not just right that could cause it to back fire. It could be running lean with not enough fuel and too much air, or could have too much fuel and not enough air. It could be because the intake valves are not shut when the combustion takes place, therefore the combustion would take place in the wrong spot. The most likely cause are from: 1. Incorrect timing, the timing issue could be caused by bad wiring/ or bad ignition. 2. Incorrect fuel to air ratio, bad fuel filter, low fuel pressure-caused by weak fuel pump.
What do you do when your 1989 Buick LeSabre 3800 either idles too fast or too slow and sometimes wont start or stalls?
There could be many reasons including the spark plugs may be worn or not gapped properly if the car does not idle right, faulty spark plug wires, vacuum leaks, incorrect ignition timing, incorrect compression ratio. The culprit could also be the EGR valve or plugged PCV valve, fuel pump not delivering fuel properly, timing chain worn. I would suggest get the car check out.
What would cause a 40amp ignition batt fuse to blow on a 97 Malibu?
There is a sort somewhere in the starting system
What would cause gas to come out of your exhaust?
incorrect engine timing so that it misfires
Why would your 71 Chevelle stall in gear?
Number cause is a vacuum leak. However, there are several engine tuning issues that can cause it.... Incorrect idle mixture, fouled spark plug, incorrect ignition timing or dwell. You name it. But I've found that sizable vacuum leaks cause it more often than any other single cause.
What would cause a car to sputter when it accelerates?
bad fuel bad spark plugs incorrect timing
Can you cut your catalytic converter off your dodge Dakota 1998?
It would not be a good idea. First it is illegal, second it can actually cause the computer to over adjust fuel and ignition timing and cause running issues.It would not be a good idea.

What would make 95 Honda odyssey sputter and backfire?
Incorrect ignition timing or damaged valves would make a 95 Honda Odyssey sputter and backfire. Backfires are directly caused when ignition occurs at the wrong time.
How do you stop fire coming out of carburetor?
the most common cause is incorrect ignition timing. your spark plug wires are in the wrong order or your distributor is misadjusted, whoever did your tune up last time is responsible for the problem. Otherwise it would be caused by a misaligned valve timing chain or belt. If it ran before or while it shot fire out the intake, its probly not the timing chain/belt. if you recently removed or replaced that, you should be smart enough to correctly adjust ignition timing. Only other cause is a bent intake valve (least likely).
What would cause the 96 Geo metro die when shift for D or R after replace water pump?
Cam timing incorrect.
What would cause a backfire on a '67 Mercury Cougar?
the ignition timing set wronge. BAd accelerator pump in the carburetor
What would cause a 1957 Chevy to backfire and not stay running?
Incorrect timing, spark plug wires not installed correctly, timing chain worn out and has jumped a tooth, or distributor worn out.
Would advanced or retarded timing cause intake backfire?
yes, backfiring is always due to ignition or timing problems. Backfiring through the carb can be a symptom of a lean condition.
What would cause black smoke on acceleration in a Mazda 6 diesel?
Fouled, damaged injectors or incorrect timing on fuel injector pump
Would a loose distributor cause your car to not start?
Yes, a loose distributor can rotate so that the ignition timing for the engine is lost.
