Just bought a 93 GT with a V2 (non intercooled) vortec SCi running 10 lbs of boost. It has a lot of bolt ons to include 42 lb injectors, edelbrock heads, full magnaflow and bbk exhaust, tremec 3550 w/ tri ax shifter, an f cam, single walbro 255 pump, etc...
In warm weather, it hesistates and loses power (runs very rough) in the mid range RPMs. I have cleaned the MAF, put in a new fuel filter, and changed the plugs (autolites), and it still hesistates. My wideband A/F jumps around a lot everywhere from 16:1 to 13:1 with no boost. It runs anywhere from 180* to 195* (water temp) when it is hot out. In cool weather, the hesitation doesnt happen.
Any ideas? Please help!
Do I need colder spark plugs?
