Rough Idling on 91 940 Tubro 900


My 91 940 Turbo wagon is idling rough lately, eventhough when I step on the gas it runs smooth. Any thoughts ? And would it be an easy fix for a novice "mechanic" do-it-yourselfer, like me ?

Check the condition of the throttle body (when was it last cleaned?) then check the FAQ's. Other possibilities include plugs, wires & cap/rotor (when was its last tune-up?). Both are easy novice DIY mech. fixes.

Rough Idling on 91 940 Tubro 900

My 91 940T sedan was doin the same back in October. Definitely look into the spark plugs+wires. The distributor cap and rotor should be looked at as well. The cap and rotor were the main problems when my car did that.

Thanks rjk and aznmandan83! I guess I did not think of that since it runs smooth after I step on the gas. But I think it is time to change the spark plugs.
