Re: need help again

Will it idle at a slightly higher RPM? If so I would place a dime/shim under throttle stop screw and witness the spray pattern of injectors. Even conical spray should be seen. fresh fuel filter?

Re: need help again

what does spray look like? I think some will shine timing light on spray to better determine quality of spray. Any codes stored?

Re: need help again

ok ive changed the distributor cap and all of the spark plug wires and plugs ..my car still surges i got some throttle body cleaner and sprayed it on my car started to run a little bit but then died so i opened up the throttle body and sprayed it in while it was on ..i think my fuel pump isnt sending enough fuel to the tbi ..does this sound reasonable
