Xtreme89

So a week or so ago I broken down where the car would just barely idle and would Rev to about 3000 with very very light throttle input, also it would make boost our of gear (5 psi or so), any further throttle it would misfire bad.
At that time I was getting codes for misfire random, cyl 1, cyl 2, cyl 4 and P0030 - oxygen sensor heated control circuit bank 1 sensor 1.

So I replaced the primary o2 sensor. And now the car runs and drives good.

Except when cold it takes give or take 10 seconds of turning over to fire and run.

Also it's now in limp mode with limited boost. No more misfires but with code P1128 bank 1 too lean

I have changed the CTS and done a boost/vacuum leak like described in a4 mods and found 0 leaks as well as changed the plugs and went with the NGK coppers, still had the hard start and lean code with the oem specified plugs.
Here's a log of 2nd gear pull showing the lambda pegging at 25% and the MAF reading looks good.
