Car is sputtering like got bad gas


have you recently purchased gas? that's 1st question. if you suspect bad gas, add 1 bottle of CLEAR rubbing alcohol to your fuel tank,this will dry up any water that has been added into your fuel tank. or perhaps your fuel injectors may be clogging up,suggest that you add lucas fuel injector cleaner to your fuel tank. you can find the lucas at any auto zone,advance auto parts store. or check your local auto parts store for it. add it to your fuel tank and run the engine,it cleans your fuel injectors as you drive the car,or run the engine.if this does'nt help,i suggest that you check for bad spark plugs,or bad spark plug wires. this will also make your engine sputter.do you have a check engine light on? if so,auto zone or advance auto can code read your car for free. they will plug it up and tell you which sensor is bad or what you need to replace to make the light go off.narrow your search by ruling out this 1st {bad fuel} {spark plugs in need of replacement,or spark plug wires in need of replacement} hoping this helps,and thank you for choosing fixya.com

Engine stalls when turning left hand corners.


turn left, sputter, sputter, pop! sputter, sputter..............vvveeerrrooommm !? WTF? Crazy 91 Honda CRX just became a death car tryin to get through an intersection. Checked all my wires and ended up in the gas tank tryin to put the fuel pump back together. POS pump is in the left side of the tank!? So if you got a few miles on it the fuel pump screen can fall off. Turn left and the last 1/8th of a tank goes to the right leaving a 3/4 ton chevy in your girlfrends lap...well almost. I still got the CRX, the girl got droped off at the car wash cuz she smelled like poo.

While idleing engine quit running and won't start unless I manually feed it gas, gas is getting to the motor at back end but appearnetly not to the enjectors 1993 v6 vortec motot any suggestions


The fuel injectors need between 55 & 60 pounds of pressure to operate correctly check the fuel pressure next time it runs if the pressure is low needs a new fuel pump or fuel filter is clogged. Try the fuel filter first if it has never been changed, it's cheaper and should be changed regularly anyway.

Audi 1999 a4 runs rough idles up and down


I think the fuel has gone bad. it's cloging the injector ports. Try this first remove all fuel from the tank, replace the fuel filter. add 5 gallons of fuel and one bottle of fuel treatment. Run the engine for an hour
this will allow all of varnish from the bad fuel to disolve and clean the injectors. Don't be suprised
if this doesn't totally elimnate the problem chances are the plugs are fouled and need to be replaced also. Good luck
Hope this helps

When my 2000 Pontiac Gran Prix accelerates to about 4000 rpm it acts like one cylinder is cutting out but runs fine up to that point. I have replaced the coil pack assembly and the ignition module plugs,...


The fuel may be contaminated,use a bottle of lucas,and two bottles of heet in the fuel tank,this will take care of the moister in the tank,and clean the injectors,and fuel system.
