Any STS users experience misfires after install?? My buddy put an STS on his car last week. We started tuning it, and noticed during idle and sometimes not, the SES flashing and then going steady. I scanned, misfires! I pulled up the misfire pid (not exactly sure which ones to scan but) found misfires on Cyl #2, #6 and #7. More in 2 (100+/-), then 6 (80+/-) and 7 (70+/-) had the least, other cylinders were 0. Checked the plug wires secured to the coils, check and plugs check. Later we found the injectors were not fully seated and locked in, creating a leaking around cyl #3 & 5 (he replaced stock inj. w/ Venom 60#). Seeing how the LTFT on bank 1 was 4 and bank 2 was 14, thought air was getting around inj seals. Will check this tomorrow.
Just wanted to see if maybe other ppl have seen this, backpressure issue? or something? TIA,

Well I would hate to burst your bubble but we have had the same problem with 2 sets of Venom's we will not be using them anymore, turns out the lean misfires you get are due to the fact that some of the injectors flow less than others and when you get some running good, then the others run lean and visa-versa. They are junk, (ever noticed how banged up they look when you get them?) and unfortunatly you get what you pay for...sorry to be the bearer of bad news.
