Which fuel system do you have? Carbs (better not be with 30+ PSI of fuel pressure!), D-jetronic FI (stock 1.7, 2.0), L-jetronic FI (stock 1.8) or other?
You need a gauge to set the fuel pressure. Period--you can't set it right without one!! High idle is usually caused by air leaks. Less often, it is caused by overly-advanced timing. --DD |
