Carb is dirty or engine is low on compression should be 120-130 psi compression.

Pull out the air filter (carb) and see if it looks clean and does not have any oil on it. Check your fluids. Adjust the choke.

Engine stalls on Isuzu I-370 truck after warm up


The Cam sensor usually senses the position of the timing belt or timing chain gear and tells the computer when #1 cylinder is at top dead center. In other words, when #1 cylinder comes up. Crank sensor tells the computer when to fire the spark plugs in the rest of the cylinders. In other words, as the crank shaft goes around it tells the computer when each piston comes up so it can fire it's spark plug


so replace the crankshaft sensor

My 2007 FXDB cuts off at stops after getting hot. Restarts readily but seems to fire off really hard. Will idle fine after restart but next stop dies again.


First off I would raise the idle just a bit.

If you have been getting gasoline with 10% ethanol that could cause the slower idle that lets the engine die.

One more thing could be the gas cap is not venting to let air in. You need to be at a stop for this. Don't try it while riding.

Crack the gas cap loose just a hair so it can breathe. If that fixes the problem, get a new cap.

One thing I do every 5,000 miles that has proven beneficial. I go to the Dodge dealer and buy a bottle of carburetor/injector cleaner. Not the kind with mineral spirits, get the really good one with naphtha. I have only found naphtha one time at an auto parts store. you can try looking there if you wish but I doubt you will find it.

Car struggles to start struggles to get up to speed struggles to idle


Sounds like a miss fire, try a tune up if its been a while since your last one. Plugs wires air filter, etc.
Look at your exhaust with the car idling, if its dark grey then you have unburnt fuel in your exhaust and a tuneup is a good place to start. If it is blueish grey then you are probably burning oil and may need an intake gasket or valve seals.
Also check your fluid levels, especially coolant and oil. if the oil level is high and the coolant is low you may have a deeper issue and may need to take it to a repair shop.
