So i began a thread over in Engine/Transmission/Maintenance . but the focus has switched over to more of a forced induction Question. So here whats is going on, last saturday night i took the car out for a ride. eventualy i decided to open her up and i did but soon there after the car started haveing issues boosting.
the best way to described whats going on is that when i get on it at about 3000, give or take a few rpm's ,it begins to just bog down and back fire. i believe its misfiring. it only happens when the car hits around 8 pounds of boost. odd thing is that my a/f is staying around were it used to . 13-11 range. the spark plugs are gapped to the correct gap .30 . my head gasket is good 205 - 210psi accross the board. it has new plugs and wires . the cap and rotor look good. i tried going back to an older fuel map to see if the problem would go away and it stayed. i should also note that the issue happens 90 percent of the time but not always. i am running out of ideas and could use some help. ps here the other thread i started http://www.6gc.net/forums/index.php?showto...mp;#entry654965 -------------------- |

QUOTE new OEM wires, cap and rotor, once a year. at least Toyota really gave us a crappy EFI system with these cars. I mean, todays modern cars can go at least 60k without changing the ignition components, even the turbo ones. Im willing to bet that we wouldnt have so many ignition issues, if we had coil packs instead of a cap/rotor. Megasquirt is looking better and better every day. -------------------- 15PSI - 30MPG - Megasquirt Tuned
