I called the mechanic today and he said he didn't touch the balance shaft belt, although he did check it. It was fine. Ok guys heres the deal now, the car runs flawlessly after I warm it up to operating temp (ofcourse) then I do my first boosted run, 2nd, 3rd, 4th.. flawless. I slow back down, second run is crap and sputters on top and never really hits peak boost. This happens every time I get in the car. What's going on?? And i logged the coolant temp and it's being read by the ems and seems to be functioning normally. Nothing seems to be wrong in that respect.

 

^^^^

 

Autolite, Double Platinum, APP3924. That was my problem, this whole time. These plugs SUCK. I went to some good copper NGK BPR8ES. Gapped to .024. Perfect running again. I believe my through-out bearing is next to go. haha. Thanks everyone who tried helping me, I really appreciate it.

 

WOW your great mechanic just opened up the box and put them right in with out gapping them. and on top of that using crap plugs. makes you 2nd guess if you want to bring your car back to him. i wonder what kind of oil he put in your car? you might want to check that.

 

Yeah, i'll never bring it back to him. He also left the thermostat housing with two bolts missing, one finger tight, and one was tight. I was driving and coolant and steam sprayed everywhere. I was glad it was just that, but, i was pissed. I went through most the stuff he put back together to see if it was all done correctly after that incident. GRRrrr... Anyways, the engine has royal purple, I made sure of that. I'l' keep an eye on the fluid levels for the next couple weeks.

 

BTW.. FL_SilverEvo8.. 400+whp and stock turbo. BADASS.

 

Glad you figured it out.

 

Thanks man.
