Why wont my '74 f350 stay running?


Check your timing. Your timing chain may have "jumped". They usually do that as you are shutting the vehicle off. Turn the engine over until the timing mark on the crank is at 0 on the pointer. Pull the distributor cap and see where the rotor is pointed.It should be on #1. If it is a long way off, like on the other side then rotate the engine 1 complete turn and check then.

Intermittent fuel starvation,high rpm at idle restart eng all ok


You should verify you have proper fuel pressure. Check with a gauge when cold and hot. Possible clogged fuel filter is not allowing enough gas to feed engine. Verify pressure at idle and also under load when driving.

Idles good, dies when i put it in gear


I had a very similar problem except I would have to throttle my truck just to keep it running. It wouldn't even idle. If I were you check the spray pattern on your fuel injectors. It should look like a nice misty cone. Youy dont want lage drips of fuel, you want a mist. Also cut into your fuel line to test your fuel pressure. It should be around 9-13 psi. My truck had 3psi. I then replaced the fuel pump and the problem was solved. Hope this works for you.

Engine starts,reaches high rpm,then slowly returns to a rough idle, misses badly,no backfire,surges as if searching/adjusting air/ fuel/est,timing light shows mark constantly changing/erratic,engine then...


Vacuum leaks. Check all hoses and intake bolts. Leaking EGR or plugged PCV valve. Air filter plugged. Leaking head gasket. Worn timing chain. Camshaft lobes worn. Valves burned or leaking. Fuel idle control system or sensor. Good luck!

1998 boxter idle is perfect ,,missfire /backfire when rpm is incr


It might be injectors and/or fuel filter clogged.
Try to use injector cleaner (ask for recommended heavy duty in auto store) also I would check maf sensor.
Also misfiring/backfiring is a sigm of worn/damaged distributor cap/wiring
Please kindly let me know if this info was usefull/useless for you or you need more info
Good Luck

98Eclipse 2.0 nonTurbo 5speed 180,000 miles ,code PO301


The po301 is a misfire code. The backfire can be caused by a excessive amount of fuel, bad valve timing etc.
My guess is you have damage to an exhaust valve that may have occurred when you had the timing belt problem.A compression test will indicate if you have a leaking exhaust valve.The reason for the backfire is the exhaust valve is still partially open when the spark plug fires.

Ran out of gas and now she won't run!


i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.
