Just a thought...it may also be your throttle postion switch.

I tried to find a vacuum leak with propane but no success,

no audible hiss either, would the throttle pos. throw an alarm?

I checked the plugs and they look ok, at night I can see no

arcs in the ignition. don`t know how to test the coil in the cap

except to replace. Normally I would suspect a #32 egr problem

as this has some of the earmarks but again no code or svc eng

light. Well maybe try to put a cap and coil on tomorrow. any other ideas

appreciated!



TIA Dave G.

I would look ar removal of the throttle body for a complete cleaning.

Do not try to do it on the car. Just for grins, I would also replace

the throttle position sensor and set it properly with a digital

voltmeter. Neither if these tasks are very complicated.
