SOURCE: Stalls when engne warms up

Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.

SOURCE: 91 jeep randomly wont start; also spits/sputters on acceleration

First (I"M starting to sound like a broken record on this) check the ground connections at both ends of the cable.(smaller body grounds as well) Make sure they are clean where they make contact with block and terminal post (not just on the outside.) Make sure hot wire is also clean and fastened correctly. Right now, we are trying to find out what it's not., Then, you can get to what it is.Often small stupid things can look like other larger problems.

SOURCE: 95 jgc laredo spitting and sputtering , will not idle dies

You may want to check the Idle Air Control Valve (IAC). It is located on the back of the throttle body and very easy to change. You may have some luck just cleaning to see if it makes a difference and then you can buy a new one.

SOURCE: 1999 grand cherokee limited stall's out while driving

Check spark first if ok then look at the fuel system.Check if the fuel pump is working continuously when turning the key.If so remove the fuel line to the ejectors and check if there is fuel there.If no change the fuel filter.

you may have poor ignition wires that need to be replaced or a bad electrical connection that is affected by water either for the ignition system or the fuel injection system. just some places to look.

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
