Curious...What did the compression test show...You stated in a previous post it started running bad...was this out of the blue? Do you use it to haul a trailer? Interested in the compression test...These motors are pretty easy to work on...If you think it is a vacuum leak...Pick up a can of ether and spray a little around your intake and vacuum lines if the motor revs up you are in the right location...also with the motor running pull one plug wire at a time and you should see a significant change in the motors idle if one of them don't change the ideal you should check that wire,plug,and compression on that cylinder...Sometimes with those little 22R motors changing out the coil can help...For some reason when you do the test they hold the suggested specs. but under a load they fail...Just make sure if you change it you stay in the range for that motor or you will burn a piston out...
If you have never changed the Timing chain and guides you should take the time to do it now while you are into it this far anyway...This should be done every 65,000 miles...They are not that expensive to purchase just time consuming but you will have to do a little work and take your time follow the book if you have never done one before as they can be a little tricky...

Good luck and Please do keep us posted...

also,

plugs are ngk, new, gap is set to the specs went back thur made sure all the wires to the plugs were in the right order.

I hear ya brother sounds like a plan...Those motors are not real bad to work on I actually enjoyed mine...Good Luck Buddy...Let me know what ya find as I am curious now...

its 1 3 4 2,

the wires are good.

have not done the compression yet will do it tonight or tomorrow. last year had a head gasket leak, took the head off replaced the cam, had the head checked/ put new injectors, cleaned all parts replaced all rubber lines and used new gaskets. while i was in the motor then, it appears that it is on its last rebuild, pistons were 3 over, i think. if the compression is bad i will prob pull the motor and use another block that i have and just rebuild and start over.

Good point...I would look at this also...before you start a rebuild...Small price to pay...

I think part of the problem could be a bad intake manifold gasket leaking on the bottom side. I have replaced several aftermarket gaskets that get hard and shrink till they split and leak. The egr valve port will usually get stopped up with carbon with high miles on the engin, but check it anyway. Let us know what you find as I drive one also. Catfishjon
