This is a 1993 2.5L with a manuel trans with 188k. I recently purchased the jeep from a good friend who was upfront and honest about the condition and history of the vehicle. It had been stored in his garage for three years. The only good thing he did was empty the gastank before he stopped driving it. I have replaced the radiator and hoses, water pump, belt, plugs, plug wires,distributor cap and rotor, thermostat, oil and filter, fuel pump and filter, altinator,starter and battery. All wires and vacume hoses seem to be in good shape . The idle is perfect and she starts right up. When I give it gas @ higher rpm it hesitates and I can hear a loud poppng sound coming from the air box? Please help.

 

try replacing the coolant tempature sensor. Throwing any codes?

 

No engine light. It was on when I first got it. It won't make it to get coded with all the bucking and puttering it does.

 

did u put ur plug wires on the right way? sounds like a timing issue

 

I'm going to try a new cts first thing tomarrow and keep my fingers crossed. Thanks, I will let you know what happens. I did check if the wires were correct and they are.

 

Put in a new cps and that didn't fix my problem. I even put in a new fuel presure regulater . Still bucking and jerking, and popping from the trodle body?

 

i still think its a timing issue, u may have put them on in the right order, but did u start with #1 in right spot?

 

Do you think it could be my injectors?

 

Have you done a compression test?
