Check the O2 sensors. Also check the gas regulator. Also check the ignition coil not sending any spark to one cylinder.Check all the ignition cylinders if any of the cylinder burnt out it will spit and sputter also check the coil pack.you have replaced the spark plugs But check the voltage to spark plugs.the spark plugs gets power to spark from coil pack.If coil pack is burnt then it will not give required power to spark and due to this vehicle will spit /sputter. Its either the coil-pack, or injector/cylinders problem.Also check the spark plugs. resolve the issue.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Why does it miss between 50-60mph


Gas would do it all the time.Fuel filter may be stopping the flow of gas causing a misfire. It sounds water in gas but just at High RPMs like it is vapor locking (not getting the right amount of fuel). would change the Gas filter, Air filter, (gas Treatment to remove any water like Sta-Bil ).If it goes away your lucky. But it looks like a fuel pump is getting weak.

Will start and Idle great but when push the gas pedal it just acts and sounds like its bogging down. I have replaced the fuel filter its a 1.5 4cyl automatic


You replaced your fuel filter but have you checked the fuel pressure. It sounds like the fuel pump is not putting out enough pressure to get enough gas to the engine.

2001 Hyundai doesn't accuerate when it first starts. It hardly moves then slowly picks up speed.


I could b gas filter or the filter on fuel pump, or injectors most cars have gas filters on the drivers side railing on frame it's easy to change one bolt on holder and most have two clamps just remove clamps and bolt switch out put back. But be very careful it is pressurized once fuel line is removed fuel will squirt out turn face away.

My 2001 Chevy Cavalier acts like it is not getting gas, a new fuel pump and fuel filter and line was put on and it quit again on me, another fuel pump, spark plugs or points was put on and still will


Check your lines, specifically where your filter housing goes into the fuel tank. I had the same issue and I just had to replace that filter along with a hose. It seems the line somehow got clogged. I hope you find this helpful.

Truck will crank and run fine till it warms up...when im on the interstate running a steady speed it acts like its running out of fuel or lossing spark... if i let off the gas it will clear up then start...


Have you had the computer scanned? It sounds like a fuel injector problem. Injectors may be dirty. Or possibly a fault in the injector circuit. You didn't mention changing the fuel filter. I know some of the Dodges have the filter integrated with the pump. If yours has an independent filter it should be replaced.

Pickup died while driving it


You need to put a fuel pressure tester in the fuel rail and then determine weather or not you need the fuel pump replaced,if this is not the case then the throttle position sensor is likely the culprit.

I have a 1999 Audi A6 quattro, have just changed original fuel


You have to bleed the system, most likely air, or you blew the fuel pump fuse !
