Here are some of things I did this afternoon.
1. Checked fuel press....38 psi to 22 psi in 1 hr
2. Replaced all 6 plugs, gap .035 r43ts. note: removed plugs burning very rich.
3. Ran engine MAF/translator @3. af 06, L8 41, bat 13.6, int 124-134, Bl 118, mph 00, cle 162, ats 91, r 800, tps .42, iac 25, cc 18> flux. Note: during initial start...accel was ok, still hesitating. Once warmed up...hit the throttle and it just chokes.
4. Ran engine MAF/translator @2...experimenting....reset comp. af 07, L8 45, Bat 13.7, int 127, bl 115-142, mph 00, cle 162, ats 91, r 750-850, tps .42, iac 16, cc 19> flux. Once again falls flat when you hit the accel.
5. Ran engine MAF/translator @5...reset comp. AF 05, L8 37, Bat 13.7, int 123-134, BL 125, mph 00, clt 164, ats 93, r 775-825, tps .42, iac 20, cc 20> flux. Note: gradual accel eng spools better than the previous MAF settings. However, engine still falls/stalls when you hit the throttle. I'll continue tomorrow if anybody has some other things for me to check. Thanks Nick!!!
