Ok, I know the Renix system has its flaws but........
Can anyone tell me what would cause:
Cold morning (45 degrees or so) started my 89 XJ (4L) Idle settled in at 3000 PRM. Thought maybe I had a stuck throttle cable so I rev'd the engine but it settled back to 3000 rpm idle. Turned off the vehicle, re-started it, idled fine (about 900-1000) with its usual drift.
Drove it all day , with about 6 starts and stops. Idle was fine !!
So to be on the safe side, I change the MAP and the IAC.
Next morning, (you guessed it) same 3000 prm idle. Immediately turned it off, and restarted it, idle was fine all day again !
I'm thinking MPU ? Temperature sensor ? Any ideas ??
Thanks,
