I would remove the fuel filter,and blow threw it with your mouth,if it is at all hard to blow threw,replace it,if this does not help,have the fuel pressure checked to see if it is up to recommended psi,if it is not replace the fuel pump.You might try a good fuel conditioner like Lucas fuel treatment,it is the best,and Heet,two bottles of this,this will dry any moister out of the fuel.Use these additives with as less fuel as possible for a consentrated effect.Then use some high grade fuel if it clears up.This combination of the two name brand additives is a good fuel stabilizer ,and works every time if the fuel is contaminated,the fuel we get now is not like it used to be.

    The cam sensor,or the crank sensor,have the codes pulled to see if they will help diagnose the problem.Spark plugs can do this also along with boots,and if it has some coils bad this will happen also,the code reader will deliver a code for miss fire on certain cylinders to pin point it for you also.

I have a 2001 Chevrolet Silverado 2500 HD. A mechanic worked on it recently to fix electrical problems with the power window. Before the mechanic worked on the truck the Air Conditioner worked great. Now...


What engine does your 2500 HD have? Is it a 6.6 diesel, a 6.0 gas, or an 8.1 gas engine? If it's a gas engine, the A/C compressor belt may have snapped (common). The gas engines used a separate, smaller belt to drive the compressor, while the larger serpentine belt runs the rest of the accessories. Diesel engines only have one belt that runs all accessories, including the A/C compressor.

2002 Sable sedan choke/missing/sputtering intermittent


The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

What will cause a dodge 2500 spit and sputter when its cold out but not when its hot out


When hot --your working off the oxygen sensors in closed loop,
for fuel trim or control

I would look at all data with a proessional scan tool before &
after you start it.

Then compare to it 10 min later when above 180 engine temp

Some thing is a miss on start up,could be mechanical also

Keep the oil clean & use synthetic if a gas engine --like MOBIL 1

When i am driving my suzuki ignis (1.3,manual,2001)in a traffic(more than 45 mins)engine starts to miss(check light indicates) and it stops.cant start it for about 10-15 mins


I have a 2001 Suzuki Ignis and I have a similar problem. When I start the engine 5 beeps are heard and the hazard lights turn off and on with each beep. Also after I have been driving for about 45 mins 3 beeps are heard and the hazard lights turn off and on again. However my engine does not stop running. I have asked people about it and they think that it has something to do with a lose wire in the security system? Any help would be greatly appreciated!

Miss on cold start for 45 sec to 1 min then stops missing and runs fine, another thing that happens is if I put gas in it I have to let it run for 2 min or so or it will die then is hard to start .


That sounds like you have water in your gas or oil.
I would have it check out by the dealer right away.
