We have just purchased this vehicle so i am not sure about the maintenance up keep of the vehicle.
But we have changed the spark plugs to ngk ones after we found out the old Bosch ones were fouled with a yellow color on them.
We are going to replace the ICV and the FPR tomorrow.
There was a small vacuum leak at the FPR but we have replaced it with no change to our situation.
The starter also just gave out on us today, hoping to get that fixed soon.
We have also ran seafoam through the engine and has only made a noticeable difference to performance of the engine, but still no change to idle condition.
Any help would be much appreciated
