1990 Chevrolet S-10 Repair Question
Engine runs rough only will stay running if you flutter the throttle but runs fine if you spray starting fluid in the throttle body
what is the actual fuel pressure??
do you have any vacuum leaks?? especially around the throttle body.
i dont believe it has any vacuum leaks fuel pressure is about 12psi
did i mention it also back fires shoots a good flame too
verify that the wires are going to the correct plug. otherwise it sounds like it is running too lean.
what would cause it to run too lean besides the ecu. it happened from sitting for like 2 months. at first i was able to start it with starting fluid and drive it without a problem then one night it just stalled when i pulled into my driveway sence then ive been having the problem im having thats why i changed the injectors
12 lbs of fuel pressure sounds low. it should be around 15 lbs.
