sTalnOut

hey guys, i need some help ok last week coming home from work (s14 w/ s13 SR20), i was driving all of a sudden when i was on 5th gear my car seems to pause/bog and the speed-o n everything just shut right off. Had to pull over and check under the hood and nothing seems to be lose or anything so i start the car again in its fine all the way home. On Saturday drove out and the same problem occur when driving locally just cruising on 2nd gear my car would just die by itself and slowly comes to a complete stop , i have to pull over and start my car up again. On Sunday drove it to my boys crib and the same problem happen so i clean the MAF and figure this will do but i guess not.

i had my friend take a look for me n he did notice my timing was off which he help me adjust it back to normal.( i do need a new chain very soon) so i drove it around to see if the timing fixed it and the problem still comes up. But this time it doesn't just completely stall out on me it actually pauses
( like the motor bout to shut itself) while my foot is still on the gas and goes no where and started to bog like its struggling to start and then it picks up again, but everything happens when I'm on 1st ,2nd gear...

For a minute I was thinking it could've been bad gas i got for Sunoco.Anyone have ran into this issue with bad gas and if so what happened ?I'm going to try and run off all the gas i have left in the tank n see what happens.

week 2
today i drove it home n it didnt shut on me but 1 thing my 1st gear seems really sluggest and when i punch it my boost gauge doesnt seem like its goin over 5psi even when im hitting up to close to 7000rpm. Until i switch to 2nd ,3rd it starts to hit 7 psi. I do feel more power but the motor dont sound like its working proper.My exhaust sounds off as i accelerate. Im freaking confuse nor dunno where to start checking ..Could it be a bad fuel line,pump,filter? The worst its not consistent its only once awhile *sigh*

Also what is the correct reading on a fuel gauge (kg) when at start up , idling, and accelerate. ?

Please help guys thanks a million
