03 msp stall issue

I work at Bluebonnet Ford in New Braunfels, damn and I already spent $98 on it >:/

Bad news...wasn't the VICS solenoid, although since I plugged in the new one (since I'm stuck with it now) the stalling seemed to get a little better, but now I've noticed that my car completely shuts off when I shift into another gear passing 4,000 rpms and if I leave the clutch in whole going into the next gear without giving it gas my car shuts off, the only other code my car threw was a knock sensor code, could a knock sensor be causing this??

It sounds more like a vacuum/boost leak or dirty MAF sensor.

 

[TxusMSP]

Yeah I'm gonna clean the maf, where is it located?

 

[TxusMSP]

I know it may sound dumb but is there 2 if you have the upgrades piping? Because I believe I cleaned the maf if its the one right after the air filter

 

[hornsfan10609]

No just one MAF sensor, if it is before the turbo it is likely there is a leak somewhere which would cause the stall. Check your couplers for leaks.

Well looked at my maf sensor this morning and I think I found my problem, it's just that white little stick in there, I believe I'm missing the two thin wires that are supposed to be in there also?? Correct me if I'm wrong please

 

[hornsfan10609]

No you won't see any wires, if the MAF was missing any pieces the car barely run or not at all. You can't really tell if a MAF is dirty just by looking at it just use real MAF sensor cleaner, all the techs I work with used the brake cleaner we had in the shop.

 

[TxusMSP]

But I'm looking at other pictures of the MAF on our cars and they all have those 2 really thin pieces of wire in there, my maf doesn't have those right now

 

[hornsfan10609]

Like I said if the MAF didn't have those wires the car would not run or would barely run, not just occasionally stall.

 

[TxusMSP]

Well mine doesn't have them it just has that solid little white one, I cleaned it this morning before I took off to work and nope same thing still stalls

 

[TxusMSP]

I don't think it's a boost leak because it boosts up pretty fine it's just when I push my clutch in and hold it in and let my RPM's drop it just shuts off, but if I leave it in gear and come up on my clutch like let it go the car turns back on

 

[hornsfan10609]

Reset the computer and see what happens, what you are describing is a leak after the MAF sensor aka a boost or vacuum leak.

 

[TxusMSP]

How do I reset the computer?

Judging and remembering when this problem started I believe the upgraded piping on the passenger side that is closest to the ground got knocked too hard when I took this dip last weekend, I'm going to use one of the lifts at work and see if there is anything loose, I believe there will be something loose, you can see scratches on the pipe on the bottom where it might have knocked something lose let's hope this is it

I know this thread is over a month old, but did you get this resolved?
