Question about 1998 Chevrolet S-10 Pickup

2 Answers

I have a 95 S-10 2.2 when it starts it runs very rough and sputters and spits under load but when it warms up and the oil pressure drops it smooths out and runs properly with no hesitation at all. New fuel filter, IAC valve and new EGR, with PCV also.

Check sprk plugs & wires for fouling, cracking, etc. Before heading in for the $$$$ overhaul, buy 2 cans of "Seafoam", 1 in gas tank with 5 gals gas( will treat up to 20/25 gls), 1 in crankcase. This is a GREAT product that for less than $20 may hold you over for awhile if indeed you have to tear into internal engine.

Engine sputtering idle


Possibly a leaky injector bleeding down the fuel pressure. First check fuel pressure at shutoff, start, and then when it's smooth. If it changes a lot, you would have to raise the fuel rail and power on the pump to see what is happening.

05 taurus spits and sputters on startup when cold


This can be caused by a problem in the fuel pressure check valve of the fuel pump. Have a pressure leak down test run by a shop, if the system is losing pressure then the pump assembly must be replaced. The fuel pump is located inside the gas tank and is electric

My car will not start in the mornings or any extended periods of time .It will start after it has run for a while.It spits and sputters and shakes when trying to start it.When it does start and I press on...


here are a few possibilitys, a bad fuel pressure regulator . the vehicle runs rough, the engine will not start ( usually in mornings ) many times engine starts but stalls shortly after starting. a bad regulator can result in fouled plugs. replacement is only cure. black soot on plugs, blake smoke from tailpipe, running rough, stalling. make sure fuel filter is not plugging up. or low fuel pressure from fuel pump. check fuel pressure regulator first. have a good day !! the regulator if bad will cause an instant drop in fuel pressure when turned off. and it will cause a delay in building sufficient fuel pressure,.when starting.

Sounds like the fuel pump is going out. Its inside the tank. But first see if the fuel pump is clooged. take it off and see if its plugged. Check fuel pressure if you can. should be 45-55 psi

1995 Jeep grand cherokee is missing while running. When it is under a heavy load (driving fast) it runs fine. When idleing and slow driving it spits and sputters.


I have the same problem on my 95 grand cherokee laredo. Sometimes it starts out fine and after about 10 miles it starts spitting and sputtering. Then after a while it seems to clean out and run fine again for a little while. Then other times it starts out spitting and sputtering at the begining. I changed the fuel filter and that was not it. It is a 4.0L 6cyc. Any Ideas?

Thanks,
