Change your spark plugs and clean your air cleaner element, if nothing happens have your carburators or injectors cleaned

95 thunderbird backfiring through air intake

Something like this is often a stuck or poorly sealing valve. A Vacuum gauge is the least obtrusive way to notice vacuum changes. If a cylinder fails to seal, vacuum will reflect the loss of compression and it will result in a bounce on the meter.

Hey, my 1997 Bmw 328I is idleing irratically

Hi Paula, Had same problem with mine,use a can of throttle cleaner.Disconnect air intake from the air filter to the last clamp.Start car (get help) spray into intake and don't be shy about how much you spray. Rev car moderately, car will stall, and just keep repeating the process. You should see black type fluid running out, when it stops you stop.

Backfire through intake no accelleration, reset to normal by turning off and on ignition switch

This sound electrical like bad coil or even timing as when it backfires the sensors put it into limp mode which usually resets itself when turned off and restarted. Take the truck to Autozone and get a free diagnostic reading and when they plug it in it will give you a trouble code. They will tell you what the trouble code means or you can enter it in your search engine and you will get lots of info on what it could be with probably lots of other people that had the same issue and how they resolved it.

1985 porsche 924 backfiring.

Check the air filter box for a rodent nest. change the air filter. No intake air no run. Perform an OBDII scan for stored fault history.

Its a 1998 528i bmw that will start but wont stay running also there is a loud kind of backfire noise from one of the cylinders . the engine wont rev up proper even though i keep pressing the throttle...

The fact that you have a backfire noise that you can trace to just one cylinder makes it sound like a spark plug could be loose or broken. Pull out your spark plugs and examine them. On a '98, that eill mean pulling off the plastic cover, then removing the coils (need a 10mm socket, be careful with the ground wires) and then reach down in with a small spark plug socket on a long extension.
Also, look for a massive air leak on the intake. Take apart the air tubes from the air filter up to the throttle body looking for air leaks. You could also have a leak at the intake manifold gasket but you may need help to check for that.

Stumble at certain rpm kicking back


It could be a few things.

Firstly check all your air pipes make sure they have not split or are not sucking in air where they shouldnt be. get someone to rev the car while you watch the engine any suspect pipes may collapse making it easier to see.

Could also be the air mass meter or air mass sensor, these parts control the air to fuel mixture, it's quite a coomon fault from the way you have described it. You may not need to replace them try cleaning the air sensor first before buying another.

Could be the EGR valve " exhaust gas recycler! valve this takes any unburnt fuel from the exhaust and forces it back through the engine. Normally when these go you will see an engine light and lose power whilst it is on and then feel normal when it's off. Although sometimes when they start to play up you wont get a light straight away.

Does the car cough? or jump ? when at lower revs.
It most likely sounds like an air fault so start there first as it's the cheapest fix.

My bmw had a split air intake pipe causing the same thing. I hope this is helpful, if you need more info please let me know
