so far, these are the mechanical things I have tried to fix the drivability issue. I have changed plugs, wires, cap & rotor, and fuel filter. Made sure base timing is set at 10 BTDC with spout out. I have done a compression test. 165 psi at all cyl. I have done a cyl leakage test and didnt hear or feel any air coming out of the intake or exhaust. I pressurized the intake plumbing to 20 psi and sprayed eng with soapy water to check for vacuum leaks. I checked the coil with a spark tester. with the tester set for 40,000 volts it would have good spark for a couple seconds then start to break up. set at 30,000 it would spark continusly while the eng cranked. Im not sure if this means my coil is on its way out as ive only see a coil work well or just not at all. I installed the ignition box out of my old car to see if this will help but havent driven the car to know.
this is my resently built old motor in a new car so I might have some electrical gremlins that I havent found yet or an issue with my tune. the eng was running good in my old car but I have since added an Edelbrock super victor EFI intake and 1.72 roller rockers and a 05+ slot style MAF in a 4" pipe.
any tips or sugestion would be great. how do i attach my curent tune so, if anyone has time, they can check it out to see what Im doing wrong and let me know so I can adjust. thanks.
