I bought a set of 120 trick flow injectors from a member here. I swapped from a set of 83 semiens deka injectors.
Installed the injectors and changed the cc's in the BigStuff3 to 1260 cc's as per trick flows site.
I start the car and it was at 15.9 AFR through out the rpm range and I developed a miss under load. It idled fine it was just lean.
I changed the plugs and it started and ran fine even under a load on the trans brake, so I thought it was fixed and just a fouled plug. So I let it idle to warm up to change the oil. I go to drive it and it's missing again. Now it is in the low 11's AFR and now it doesn't seem to change no matter what I set the injector cc's at. I have had it from 1100-1260. And I also have changed the pulse width with no change.
I even did a compression check to be sure it's not something with the engine.
I wish I still had my 83's to swap back to but I had to sell them to upgrade.
I am lost here, short of taking them out and sending them off to get them looked at, I don't know what else to do. They was supposed to be cleaned and flow as per the seller.
Any ideas would be great.
Thanks Larry
