Hey guys, just got my swap all buttoned up.

First things first. Swap wasn't hard at all. The only problems I encountered were hood clearance and swap from large cap HEI to remote coil HEI dizzy.

First question. Right now I'm running the stock 305 chip until I can make it to Tomball so 1bad91Z can burn me a new one. What should I set my fuel pressure at so I can quit puffing black smoke when I get into the throttle? I have FMS SVO 24# injectors that replaced the stock 19#. I originally had it set at 43 psi but I bumped it down to 40 psi but haven't driven the car yet. I also just hooked my o2 sensor back up. Will it make that big of a diff.?

Second, I'm having some irradic idling problems. Sometimes, it will idle at 700 rpm in gear and 1000 in park, sometimes at 1100 rpm in gear and 1500 in park. I know I prob need to go back and reset the IAC and TPS but why would it switch between the 2?

Third, i'm having a problem that I had before the swap. When slowing down approaching a stop sign, light, etc, the car will idle, then stall out for a split second but never actually fully stall, just a sharp drop in rpms. Usually does it 2-3 times then will go back to normal. No idea on this one...

Thanks for all the help,
Herb

 

I had similar problems with my idle and it turned out to be vacuum hoses. After clamping those all down nicely All of the inconsistancy went away (minus the miss b/c I've yet to change the sparkplugs (kcuf you edlebrock headers)).
