Is the vehicle diesel? If so you have a heater plug problem, or low compression, compressed air in the cylinder is not hot enough to cause ignition of the diesel in a cold start situation. Carb cleaner is more volatile than diesel and explodes easier, so the vehicle starts. Heat retained by the engine allows it to start, then when it has gone completely cold, you have the same problem, Check operation of the glow plugs and the engine compression (worn engine)

Check the ignition module (located in distributor, under cap). These modules not only control ignition firing but also send a signal to pcm to control fuel injectors. They can become heat sensitive and fail intermittently. Most auto parts stores can check these modules if you remove and take them in.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

Sounds like a faulty fuel pressure regulator, or possibly the MAF sensor.

Have a 90 f-250 5.8 gas burner. sat in a warehouse for 2 years. new battery and gas. starts and idles great. run up rpms for 2 minutes and it starts choking out. let off fuel and goes back to idling...


Carburetta is fouled. Run fine on choke - rich mixture. As it warms up and choke pulls off, its starving for gas.
First try adding fuel system cleaner to the gas tank. Do NOT go overboard. No more than double the recommended mix ratio.
The alternative is to remove the carb, open the bowl and spray out the jets and venturi with carb cleaner.

Its possible you may help it by removing the air filter and spraying every orifice you find on top of the carb. With carb cleaner. Be very carefull not to flood, pool carb cleaner in intake as this is not healthy for engine either. You can do this with engine running, so as not to pool, but slowly is best, both in engine speed and volume of carb cleaner.

Just had air intake hose replaced. now the car is throbbing like a V8 in all gears, with quite sluggish acceleration. any ideas?


Hope this helps you:
First of all I'd suggest cleaning the MAS. (Mass Air Flow Sensor) This is a sensor located in the flex air intake hose.
Now a word of CAUTION! This is a delicate sensor. It has fine wires inside, picture a screen on your house windows and 1 or 2 fine wire sensors. DO NOT clean these sensors with brake cleaner, carb cleaner or alcohol!
You can pick up some electrical contact cleaner which is suitable for this job at a local auto parts store. Spray the wire area well and allow it to air dry before you re-assemble it. Air dry is another important thing to remember, you really don't want to touch the inside of the sensor!

While you have the air intake hose off, take some carb cleaner and soak the throttle plate. Let it sit a bit and then open the throttle plate and wipe out the disolved residue with a clean shop rag. Using the rag, spray some carb cleaner on it and finish wiping the throttle plate and adjoining area till it's clean. Of course you do the above with the engine off!

These are some very inexpensive fixes that should be done every couple years depending on the mileage you put on. They will cure a lot of drivability problems...and possibly the problems you have
