Since you replaced the head gasket, your timing marks are off, and I pretty much am totally positive on this. The timing marks on this one are tricky. When you replaced head gasket, did you replace the timing belt and tensioners?? Do a compression test on all cylinders and make sure they are all within specs. If it sounds like it's only running on three cylinders, you have a dead cylinder which could mean broken or badly worn piston rings. From what you described with the backfiring and all, seems that your timing is off a tooth or two yet do a compression test first. Disconnect the fuel pump fuse and remove all spark plugs when you due this. Let me know your progress and i hope this helps. One other thing you should do since the car sat for 5 months is take the gas tank out and get it cleaned out, bad fuel sitting so long.

SOURCE: 91 honda civic dx. Starts, runs for a few seconds then stalls

Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.

SOURCE: '95 Honda Civic EX will not start after cleaning fuel injectors

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

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?

97 ford Taurus runs ruff backfires


I would suggest you start with the basics. Check your wiring on your spark plugs to ensure they are in the right order. If you can grab an OBD scanner, I'd start with it as well. It can reveal many mysteries. Your running rough usually sounds like a timing issue. If there are over 100,000 miles on the vehicle, the timimg belt will be suspect.
Best of wishes.

Why would the air pump check valves burn up?


Has the truck been backfiring or running ruff? If so it may have cause this, or possibly just failed if you can post a picture of the valve it would help to determine the case. However, I would suggest replacing the valve and Air pump, and move on.

I have a 1995 ford f250 5.8 gas first thing in the morning I have to shoot ether to get it to start after that starts right up idles a little ruff under heavy acceleration it sputters backfires and wants...


Sounds like your fuel pump starting to die. It is not getting enough gas under heavy acceleration which is 100% fuel pump slowly dying. At start up it might not be building up enough fuel pressure to feed the system but the shot of ether and engine cranking helps pressure the system just enough for the fuel pump to trickle the gas and run the engine at low rpms.

My 5.4 is idling ruff. Runs real ruff in gear and


You have an overrich fuel condition.
That will make the Cat over heat and in time will ruin it.
Check for codes
Check for misfires
Check O2 Sensors.
Fix the engine driveablitiy issues, and hope converter is okey. Not likely if you caught it so late ,it is red hot.
A ten year old converter being clogged,would seem to me, to have been helped along ,by lack of necessary maintainance on the engine
