Blinking CEL with 5 cel codes massive power loss help please :o

[Bizzarostormy]

Hey guys, couple of questions. My msp recently started driving terribly. It sounds like a lawn mower, has no power and is throwing 5 cel. The codes it is giving me are po300 (we all get that one) po102,po103,po131 and po134. I have looked these up and came to the conclusion that I needed a new MAS. First thing I did was buy the new mas and some carb cleaner. I cleaned out the old MAS and started it up. It ran fine for about 15 mins. Then the car started to idle rough, and have zero power. So I go and put the new one in. It runs fines for 15 mins of driving it around, then it goes into the same problem. I was told if I unplugged the MAS and the car ran better the problem was the MAS. I unplugged it and it ran perfectly. When I plugged it back in when it was running the car shut off! Did I pick up another bad MAS? or could it be an o2 sensor gone bad? could it be a clogged CAT? bad coils? I am so stumped right now.
car has 96k boosts fine, FMIC and injen CAI that have been installed on the car for about 6 years.
Thanks so much

if you have the torque program you could graph your signal from the MAF and see if its faulty you could also do the same for your 02 but if you have no way of seeing your signal its hard to say..

I wonder if I can pick up a bluetooth obd somewhere local.

check ebay maybe someone local near you you maysell also craigslist. Theres always people on there claiming they can clear codes maybe they are using the program

getting one sent overnight from amazon. Any other thoughts?

Check the wires on the coil pack. Where the connector connects. I've had a wire slip out of that harness and mine did the same thing it was running on 2 cylinders

For code p0300 i have seen the EGR valve stick causing a rough idle and stalling. The code p0102 and p0103 that has to be internal MAF sensor or wiring those codes are for circuit high and low.

Check for damaged wiring.

Thanks guys, it ended up being the coil pack. Crazy it threw so many codes car is running like a top now!

yeah its annoying that there is no specific coil code for these cars...as a p0300 can be thrown from an EGR getting gunked up, a purge system malfunction, a failing fuel pump, etc...as well as the coils...

The difference being a dead coil makes the car 100% unmovable...it'll idle sort of...and thats it...and because of the way coils pull current and 'charge', they can very often start messing with draw from other sensors...giving all kinds of pending codes that could be entirely unrelated...

So glad you found it dude, p0300 is a b**** for sure...
