Title: Finally found the gremlin in my motor
Post by: Soul on July 10, 2013, 09:26:47 AM
So ever since I swapped to EFI it ran kind of like balls. First issue was the pickup and TFI were bad in the mallory dist (brand new, not second hand). Second issue is I had the fuel setup a bit backwards, I had the reg before the fuel rails which apparently doesn't do its job right. And finally the stupidest thing, ever since we swapped to the EFI and retimed it, it ran like . Would get up to temp and wouldn't idle, die at stop lights and be super hard to start like the timing was way fast. After doing a ton of research about almost every nonstock new part on my car I found that Pro-Race harmonic balancers have a rep for spinning. Sure enough i pulled and compared to a ford racing balancer and it had rotated enough that 30* was past 30* on the ford one. Swapped balancers and proceeded to drive the snot out of it. Now it has a hiccup at tip in but I think its a vac leak or dirty injector. Just finally glad I'm making progress again after banging my head against the wall for months.
