Hi

Thanks for using FixYa. The stalling issue might be due to a fuel delivery problem. Also check the fuel pressure regulator and the fuel pump. Due to ruptured diagram the fuel will leak into the intake and will cause stalling. To adjust the fuel trim disconnect the battery and switch the ignition on for ten minutes. Now connect the battery and start it and let it run for more than five minutes. To calibrate the IAT, drive it up about 45 mps for 15 minutes and let off the gas. If still the issue persists, then there is something disconnected or timing belt is not installed properly. Please also check the spark plug and throttle shaft bush on throttle position sensor.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

    You need to get the fuel pump checked.

I have a 1996 dodge dakota 2wd took out the 5.2 and put a 5.9 in headers no cats no 02 sencers and my problem is when i start it cold idle is good but if i take it to 2,000rpm it will bog down then...


Without input from the O2's, the engine goes into fail-safe mode and runs in a full rich fuel trim. When the engine is cold the spark plugs are being "loaded up" with unburnt fuel, and engine stumbles. Hope this helps.

Old school proplem solver


ok this can be applied to just about any vehical ever made ...but my experience is with ( for this case) my 1991 jeep cherokee..i had all kinds of proplems and codes...they consisted of hard starting, reving up and down, cutting out,(engine dying), worse and worse gas milage..stumbling..o2 sensor codes( fault o2 sensor)..bad isc motor..bad map sensor...bad temp/thermostat and my brakes kept getting worse..(softer and softer...so i started posting my proplem all over the net and even broke down and took it to a jeep service center...i spent well over seven hundred dollars and still most all of the proplems remained...so i referd back to an old and very simple way to search for proplems with any motor...(cheapest way first)...lol well i guess not first..at least not for me haha..i started unpluging the different sensors while the engine was running to see if there was any change and every one seemed to change things a little ...so i then took a can of carb cleaner and started spraying ever gasget surface and vacume hose...!!!!..i found that the engine changed pitch every time i sprayed the intake gasget...!!!..so i bought a new one for ten dollars ...spent 4 hours to replace it .. and it fixed every one of the proplems i had...it sounds crazy but if you put a little thought behind it ..it makes perfect sense...o2 was reading faulty and lean(more oxygendue to leak)..brakes were getting softer(due to drop in manifold vacume) map sensor was reading faulty and causeing stumble and cut out (also due to drop in manifold pressure) temp/thermosate reading due to idle air temp (which needs to coencide with temp sensor) not recieving proper air flow reading also due to leak...well as much as i can go on about this i am just posting this where i can i hopes that my adventure saves someone a little money....remember i spent over 7 hundred before figuring out this simple ten dollar fix!!!! and since the intake and exhust share a common gasget it is pron to leaks....good luck and i hope this helps

Engine stumbles then dies


check to see if you have coolant in your engine oil. those engines have problems with the lower intake gasket leaking and this puts water/oil ito your combustion chamber, also runs hot after it gets worse. I would say all of those engines do this after a while.

I have a 94 chevy lumina it idles high in park and when i put it in gear it stalls i have replaced (one of the o2 sencers, egr vaule, map sencer, trottle sencer, and another sencer but not sure what it is....


throttle position sensor can cause the high idle as will a hole in the egr valve tube as far as stalling as soon as u put in to gear could be torque converter not unlocking but id check the egr tube first
