If all plugs ,wires etc have been done, next i would confirm proper fuel pressure, then I would check throttle position sensor. An old analog ( with sweeping arm) multimeter on ohms, remove connector at TPS and connect to 2 of the pins on TPS .(throttle position sensor) Engine off, rotate throttle, or have someone push it from inside, slowly, gradually and needle of multimeter should sweep across as well, if not try different combination of 2 pins. When you find right combination that makes needle move when throttle pushed, observe the needle as someone pushes throttle slowly and steady from slow to wide open. If the needle jumps, or falls off and comes back up as throttle steadily pushed, then replace the TPS. If the needle slow and steady moves up /across and no stumbling, the TPS is probably ok. Make sure you test it a few times at least.

SOURCE: spit and sputter on highway

I'd spend the money to change plugs & wires & cap & rotor, if you that style ignition.

SOURCE: 95 2.3l ranger: When engine is cool, it will miss

an ignition coil and/or wires seem to cause the most trouble when cold or damp. Sounds like you have a bad coil or wire(s). Spray down ignition coil and wires with water (in a spray bottle). If the engine reacts you may be onto something. I have also seen carbon tracking on the spark plug that can cause this. Cracked coil housings are common on a lot of Ford ignition systems

Check the EGR make sure it is not stuck open. Then Check the timing and check for dirt and grease and moister in and on the Distributor cap and on the rotor check spark gap and clean plugs with fine sandpaper.

Why won't my 2005 dodge neon go over 60 or 2,500


It may not be getting enough gas. Maybe the gas filter is dirty and slowing the flow of fuel down at higher RPMs.

Sputters then dies


Most likely a lack of fuel, check the fuel filter first.

Car wants to stall while driving


Check for trouble codes first thing, It could be a number of things. example, mass air flow sensor, map sensor, crank sensor, ignition module. Check for codes first to see if there are any. That will help you get on the right track

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,

Car spits and sputters and stalls after driving a while


sounds like a fuel pump problem,with fuel pumps u can have pressure but not enough volume,try goin up a steeper hill in 2nd gear and get about 3000 rpms on the engine and see if it really drops out bad and is really gutless,if that happens without a check engine light coming on it might be yur pump and u should also replace the fuel filter at the same time,hope this helps
