got a 2.0 pinto injected sierra
its at the mechanics but hasnt looked at it yet
was just wondering if any1 could help?

the car idles 100 percent but when driven misses ive changed the coil new plugs and leads
put a fuel pressure regulater on and turned it ever so slighty and drive it (trial and error) there is a point where it is better but still misses

can any1 help? i really want this car out for the summer
