Hi all, I have a 96 Cherokee, 4.0L 6 CYL 2 WD auto trans, 200,000 plus miles. Just recently the vehicle starts to stutter when the engine warms up after 10 minutes of driving. When the engine is not under load it revs fine, but when in gear 30 MPH is the max speed. Any suggestions on what to check would be greatly appreciated.

Error codes P0132 and P0135 have been given.

Thank you.
