Question about 2005 Jeep Grand Cherokee
My jeep has a knocking noise and when i floor the gas pedal it slowly accelerates up to about 3 grand or 4 grand and then sometimes shifts. when it does shift its a really hard ****. yesterday the engine was running as if it wasnt getting enough fuel or air. and my check engine light started blinking. so a took it to auto zone and had them pull the codes on it for the check engine light and a brought up a code 300 which is a random piston misfire. so a cleaned out my throtle body and replaced the spark plugs. but i disconnected the battery and turned off my check engine light and took it for a drive and now the engine is acting like its still not getting any fuel cause it still has no power when i floor it. and still has a problem shifting. im starting to think its a computer problem could all this be caused by a computer problem? and if not what else could it be?
Just sounds to me like the timming is retarted, because of the slow accelerateing, was the code 300 the only one it brought up? it could be computer problem, but the computer only adjusts engine functions from what sensors sends signals back to it. it just sounds to me it has to do with timming, like crank sensor, or cam sensor. with it running like you say the chk. engine light will come back on in witch case i would have it scaned again. just remember what codes you get when its scaned does not always mean thats whats the problem is, its mostly a starting point, to point you in the general direction of the problem. its kind of like reading between the lines, if you know what i mean.

Sounds like you have a fuel delivery problem . if the engine is slugish and set code for random missfire more likely is starving for fuel.check fuel filter and replace it. check fuel pressure you may need a fuel pump. i hope it helped you.rate me and if you need more help let me know.
