95 dodge dakota back fires above 2000 rpm


A tune-up is always a good idea. Is the system running rich or lean? Any applicable trouble codes? Is it back firing out the exhaust? If so, I got two thoughts, either an exhaust system problem or exhaust valves?

Back fire in the intake


Bad valve timing or sensor/s connections. Read the codes. you will need a repair manual with the codes in it.

2004 astro van.started fine in the morning put rear brakes on now won't start.fuel pump works.when cranking over backfires through intake.didn't touch any wires when putting on rear br


Backfiring from intake usually indicates a timing problem. The brake job has not effect on the engine, unless you accidentally disconnected some wires in the engine compartment, but highly unlikely. More likely the timing belt/chain may have jumped a few teeth. If you have an access hole to see the timing belt and marks have a look. If you need more specific info most libraries have subscriptions to online automotive service manuals for almost any year, make and model of car, motorcycle, or whatever. If you have a library card, some will give you the u/n and p/w so you can access them from your home computer, if not then you will have to go to your local branch to get access, but it is free!

Audi a4 1.8 can't start after top was overhauled is making a weird sound like backfiring the engine dont even move please help camshaft marks was done as well as pulleys and the pistons was also put on...


Back fire is only caused by intake valve being open when a spark plug fires on a cold engine.
Recheck timing marks of cams where the drive sprocket notch of each cam shaft aligns with the cam cap mark at the rear of the head.

It has been known for the crank sprocket to come loose on the crank nose and timing will be off if this is so.
