Saturday night the car was boosting 11psi with no problems.
Sunday It drove to and from work just fine. Boosted like normal, cruised like normal and idled like normal.
Monday I didn't drive the car at all.
Tuesday I'm on my way to work and dip into boost a bit. car hits about 10psi and starts to shudder like it's out of gas. I let off the gas and turn down my boost to about 8psi then hit it again. No shudder. It drives and runs fine the rest of the day. On my way home it started to shudder under boost again but now at 8psi... WTF?
First thing I thought was my gas gauge was wrong so I fill it up. Nope..
Check the FPR and it's not leaking or anything. Pump is heard running like it always has.
So I think maybe my MAF is going dead. So I change it out with my spare and no difference. Check the coolant, oil, and vac lines. Nothing seems to be dissapearing or mixing from a blown gasket. Check the ECU and nothing unusual is coming up.
Only thing I haven't done is change the fuel filter which is at this point the only thing left. But I've never heard of a filter just up and clogging when the car is not running.
Anyone else think of something else it could be?
On a side note my Slave cyl just crapped out on my way home tonight. That was fun cuz it happened in the Mc D's drivethrough. Basicly had to launch the car out of the drive through to get it to move without stalling which scared the crap outta the poor window worker.
