Something is going bad but I do not yet know what it is.
Now turning Jeep off and restarting Jeep most everytime clears the guage readings. Vehicle other than, runs just great. Idle,s good ect..

Following has occured:
Check Eng. light comes on ( eyeballed guages and amp guage had pegged to
19 amps?
Ck. air bag light came on , then speed guage dropped to zero , then check engine light comes on? Sometime this situation just clears itself while driving.
Had 1 incident when starting, the vehicle started but a delay occured on
comeing up to normal idle speed. All guages were at zero while engine was running.Restarted Jeep and everything came back to normal????
I suspect the compute chip is acting up.
( Any idea,s). I may have to wait until erratic readings go bad and stay bad before my local mechanic can find problem.
E-mail if you like on this problem at watunni1@twcny.rr.com or post an answer.
