Sounds like the timing may be off. I would need to know what engine it has to help you diagnose this better.

SOURCE: rough idle, backfire on acceleration

check everything you can under the hood your air intake system all of it especially make sure all clamps are tight .. and make sure all vacuum hoses are good and not cracking or broken or just loose . you might run a little fuel cleaner through a tank of gas too cleaning the engine fuel system up some. just a few ideas..

SOURCE: Sudden loss of power, Backfiring, starts then stalls

The car still runs and drives, just no power and shakes badly during acceleration. Could the timing belt have jumped? Could this happen while driving yet the car still runs?

1990 2.9 bronco 2 ..bucking backfiring, and wont idle up..


It sounds like a major vacuum leak into the intake manifold. Check all of the hoses attached to the intake and throttle body for leaks including the power brake booster hose.

1990 ford bronco idles fine when you accelerate the gas loses power and backfires through the intake


Fuel delivery problem, not enough fuel on acceleration could cause backfires. Many things cause backfires, mechanical and electronic. I need more info to give a better diagnosis. Did the problem happen all of a sudden or has the vehicle been running crappy for awhile.

1990 ford bronco with fuel injected 302 idles and revs fine out of gear but has loss of power and pings when in gear and accelerating...


First thing to try would be different fuel. Use a fuel stabilizer and fill with good gas. see if that helps. Also, check the fuel pressure.

I bought a 89 ford bronco it will back fire through the fuel injection when you give it gas but not all the time


sounds like it is running lean. Check engine light on?

You mean backfiring through the intake manifold right?

A tip in hesitation or backfire is usually a lean condition. If you have a MAF sensor, clean the inside exposed wires with carb cleaner. Do no touch.

1992 Lumina Backfire - I have a 1992 Lumina Euro, 77K miles, 3.1 V-6. Under moderate to hard acceleration the engine will backfire and you can smell gas. The spark control module, coils, wires, plugs,...


I know you mentioned the EGR valve has been replaced, but you may have a bad 'new' part. I know the car is electronic, but has anyone checked its ignition timing (timing belt been looked at, I know it only has 77k on it). Is the fuel pressure regulator OK and it vacumm supply?

1990 camry, flashing check engine light, backfiring with no acceleration when gas pedal is applied , engine runs fine at idle.


first you need to find out why the check engine light is on. Try a parts store and see if they will get the code from the computer that will tell you what sensor is bad. If you have not replaced an oxygen sensor by now that is probably what is wrong. If these are bad for too long you will damage the catalytic convertor and it will rattle when the engine is running. backfiring and no acceleration can come from the 02 sensor since this sets fuel delivery.

Hello;
Most likely cause is a broken valve spring on one of the intake valves. Seat pressure is light enough to idle smooth but on acceleration the dynamics increase the pressures and the spring can not keep up. Hangs the valve open breifly and you get a backfire through the TBI.
Hope this helps.
Thanks;

Your timing belt could be broken. You want to have this checked as soon as possible to prevent any further engine problems.
