Help!!! Problems

mithralas · 03-15-2003, 09:44 PM

I finished my swap into my 68 this weekend - it has a 93 5.0 HO fuel injected system in it. I started it up and it has some problems...for ex. its running too rich and all i have are stock injectors - i do have aeromotive fuel rails though.. secondly its idling quite funny... i checked the timing and it seems ok but at idle the engine seems to vibrate (not violently but more then it should) i think i have all the vacuums in place.. at 500-600 rpm its pretty decent but when i push the throttle to 700-1000 it vibrates quite a bit but after that its ok, one more thing i got all egr stuff gone... would that have any affect?

You may need to adjust your fuel pressure and also check for vacuum leaks. It is possible that you have an exhaust leak prior to the 02 sensors which will make the computer think the car is lean and richen the mixture.
