Hey guys, I'm trying to help my cousin get his ride rolling... This car has a rebuilt streetported block showing excellent compression...it has been sitting for 3 years... After checking compression we tried to start it... We found a bad ground on one of the injectors re grounded and now she's spraying nicely... Put the plugs back in and it fired up just fine... But its Def misfiring and we can't figure out why.. Fresh plugs wires and coils and we checked for spark! All is good... What could be causing the misfiring??? It's an 88t2 with an Rtek 1.8 and 4x 720 cc rc injectors... We never checked the trailing injectors to see that they are firing yet... Possibly a stuck injector????

 

Check your spark plugs and wires first. Then make sure your TPS doesn't have a dead spot and is calibrated right.
