Several months ago I posted a problem with my 87 syncro 2.1 wbx having a very high idle. Suggestions for repair we to replace or clean the idle control valve and or the electronic part of the ICV. I replaced the ICV with another and it was great for about 1 wk. Then the idle went up slowly. I cleaned out the old one and replaced the other. Idle went up even higher. Swapped it back and the idle is high again. Swapped out the electronic part, no change. So... vacuum leak? Is that what causes the computer to think it needs more gas? Any specific ones that I should look at? Any other suggestions? thanks peter |
