Well seems we are going to be both disappointed! Replaced the switch, cranked down on the terminals and nada!! Huge backfire and just spins, no start!

Back to the drawing board

update: 15 mins later

I got it to start and run but ran as it has before, barely, then with a little throttle input it purred at 2k for a few moments. The CEL started to flash and it instantly went to running on what seemed like less than 6 cyl's, spitting sputting etc. Then I got it to rev up past 4k and it smoothed out a bit but was hard to keep up there. It just doesn't want to run on its own and smoothly. I did find what I think was a loose plug connection to the rear most pass side coil pack, after that is when it started. Now I'm wondering if coil packs and plugs isn't the next thing I should chase. The P0107 code disappeared from the CEL list so thats good. Just a 300 and 343 still...

On a side note the ignition switc did nothing for my constant blower motor running. May just pull its fuse and the hell with it.......track cars don't need a/c and blowers or radios!

Anyone have thoughts?


UPDATE TO UPDATE:

SO.......I got it to start, run(ran total of 30 mins), idle and...........I drove it!! Now, it had no power, seemed like it ran on three cyls and had 0 throttle response, I had to baby the pedal to keep it happy enough to get me home. I don't believe its the MAP (MAF). Once it was running on its own, I unplugged the sensor, system picked up on it and actually idled better for a moment then went back to its usual ways. Let it run for a while and the MAF codes went away, so it seems to be working ok. I spun the motor at rest to over 6k so I'm thinking the vario cam solenoids are working.......just doesn't have any input response. Plugs can't be that fouled could they? Bad coil packs would throw codes.....no? Damn it I'm stumped!!
