hey guys, im stumped....

i put a newsed (used) engine in my 96 cherokee, got it off a buddy, so i know that it ran fine before i put it in.

it runs, but very poorly, its hard to start, then it idles really rough, when i put it in gear to try to move it out of my garage, it stalls. any idea's on what it could be?

i had to take the distrubutor out when i put the engine in, because it was in the way, but i put it back in, i of course had to get it back in time, which is fairly simple with these, adjust the crank to TDC, then drop the distributor in either the right way, or 180° out. i have 3 jeeps total, so i know the distrubutor is in right, the only thing i think COULD mess up the timing is if the crank is one notch off on the balancer pulley, but even then it wouldn't cause that much **** would it?

i hope i explained everything ok. thanks in advance for the help!

 

any chance a plug wire got mixed up?

 

nope, they are all the same from the 96xj, my 97tj, and wifes 98xj

 

bump!

 

what about the plug ins for the injectors, are they connecting good, i chased this problem on a camaro i had for a while. sometimes you can wiggle the wire and it will start to run better

 

i didnt even think of the plugs for the injectors, when i take the dogs out i'll run down to the garage and check.

 

injector plugs are good, this jeep sat for a while, and i bought it running poorly, so im not sure of the history of the thing. i'm wondering if maybe the injectors need cleaned.

 

could be, i would clean them and put some new plugs in and start from there

 

plugs are brand new, im gonna try cleaning the injectors and the throttle body and TPS, and IAC. we'll see where that gets me
