    06 cobalt LSJ no boost leaks, broke down an cleaned blower, IM, throttle body, I used to push 17psi last winter, now I only get about 12.5 @wot also I have an acceleration surge where I build about 10psi when I put the throttle to the floor an rev to about 4500rpm but all of a sudden it drops to around 3200 an 6-7psi without lifting my foot off the pedal. Throwing codes, only pending tho but (p0101) (p0128) o2 circuit high, and just today (p0341) cleared them an just got stuck with ho2s heater. No belt slip, no tranny problems, I’m thinking it could be... camshaft sensor a or o2 (both possible with the 0341 code) boost solenoid, bad coils, coolant temp sensor, routed vac lines wrong, leaking blower coolant. What else an what do you guys think. It’s been about 3 months it’s been doing this
