That would be great. If you have one i'll send you my address. Thanks

Where can I get the tube that runs from the MAP sensor to the throttle body? Only place i've read was at the dealership. I realy can't go to the dealership in Italy. So if anyone knows a place online that i can get it at, the info would be greatly appreciated.

With me being station in italy thats going to suck, it takes about 2 weeks to get parts and i've ben looking at getting a new head anyways, does anyone know about how much one weighs.

Very possible, would it have cracked the piston or just bent the valve?

So without tearing into it any more i have come up with a conclusion. I have either bent a valve or the blue piece is stuck between the valve seat and the valve. It also smokes so i believe i did something to the valve seal. It also still has a rough idle but seems to smooth out when reved up.

It would be behind the intake valve in the intake. Didn't think It would cause to many problems. now it just runs like its misfiring and smokes a little

I bought a new set of injectors from precision injectors and while installing them the blue tip fell off into the injector bore. So instead of putting that new injector in, I put the old one back in for now. Put everything back together and started it up. The engine ran Irratic and now is knocking or a loud ticking and is backfiring. What happened?

the top one is the one i bought and the bottom is the one that came out of it

Its a 90 mj and it has the ax15 and the shifter is for an ax15

The PO messed up the shifter some how and i was trying to fix it. I tried to unscrew the knob and the threads came with it. So i ordered another shifter from ebay and the part that sticks into the trans is longer. Will a cherokee shifter not interchange with a comanche shifter?

I've ordered a new cps and i just got it friday. Hopefully it will fix the issue.

So i got my first 1990 4.0 4x4 MJ and i have bought a new valve cover gasket, cap and rotor, fuel filter, spark plugs, CPS, exhaust system, and vaccuum hoses. It has 54K on the odometer and while i'm stationed in italy I need to know what i should start replacing to insure that it runs good. Right now it will just die while going down the road. i just start it back up and keep going. What should be my next step. Thanks.
