1993 with a 96 si engine installed.
Replaced timing belt
Water pump
Cleaned tb
iac
Fitv
New distributer
new plug wiresplaced in proper firing order
All hoses checked for leaks.
The only way to start tight now is hold throttle wide open and it surges between 5000 and 7000 Tach reading wrong because engine sounds like between 500 and 1500. When let off it spews back out thru air fiklter
Cel code of 04 which indicates ckp. Just replaced distributor with new because old one threw same code . All fuel injectors spraying all plugs are firing . The battery lights also stays on when it is running and surging. Been thru all sensor and volted them and were in spect with manual. What am i missing? Fuel pressure checked fine all injectors checked fine .I am lost. If nayone has an idea i would gladly appreciate it .
