I moved the teeth on my MAF and now my car doesn't start. I tried moving it back to original setting and it still doesn't work.

Re: HELP!!! with Mass Air Flow Sensor (VeeDubClub82)
ok I see no one wants to help me. I put a new MAF in and it starts but as soon as I let off the gas it shuts off. I was told to reset the computer by dissconnecting the battery so I did that and it still doesn't work. I was also told to check the spark plugs to see if they were wet but they weren't. So I am running out of ideas. Any help would be appriated.

Re: HELP!!! with Mass Air Flow Sensor (baywindow)
how do i check for a vacuum leak if I can't start my car? COuld I have messed anything else up. perminate damage to the computer. Anything. I find it hard to believe no one has ever messed with the mass air flow sensor. But it so then I guess I should feel special.

What was the origonal problem before you messed with the MAF? was there one?

Re: HELP!!! with Mass Air Flow Sensor (gearhead455)
no real problem. A friend told me that I can move it a little and it will run faster so I tried it and I didn't really know what I was doing. I assumed that the worst that would happen is that the car wouldn't start and I would have to put it back to the orginal notch. But I guess I was wrong. I've learn not to mess with stuff that I really don't know much about. Now I just need help trying to fix what I messed up.

Re: HELP!!! with Mass Air Flow Sensor (VeeDubClub82)
You have a vacuume leak or the computer has "learned" the wrong TPS and MAF position. How long did you leave the batt disconnected? Try disconnecting BOTH negative and positive batt cables from the batt. Touch the disconnected B+ and negative cables together, this discharges the capacitors in the ECU (memory).

Did you disconnect/reconnect the AFM with the car running or with the ignition on? Could've fried the ECU. http://****************.com/smile/emthdown.gif

Dude! My buddy is having this EXACT same problem. Does your car run fine once it's warmed up???

Re: HELP!!! with Mass Air Flow Sensor (Red Baron Golf)
haven't had it warmed up yet it shuts off rather quickly. plus the fact that I have to pop start it everytime cuss the starter is blown. I'm gonna work on it tommorrow and fix the starter so that will be one less problem and it should be a little easier to fix. So If I find out it works fine if I can get it warmed up. I can also check for the other stuff that everyone said to check. Thanx for the help. Thats why I love VW owners they help other VW owners with there problems. My friend saw a VW broke down on the side of the road and stopped to see if he could help just because it was a VW. I always do what I can to help fellow VeeDubber.

Re: HELP!!! with Mass Air Flow Sensor (VeeDubClub82)
Ok I tried to work on it today. I still don't have a starter so its loads of fun to try and fix it. I took a known working air box and put it in my car. The car loads up and backfires and shuts off. its sounds like a farting noise out of the mufler

Dude, It's flooded from the attempted push starts, clean off the plugs with a propane torch and get a starter.

Reducing AFS Spring Tension
To reduce the spring tension, first remove the black plastic cover on the air flow sensor by cutting up through
the silicone sealer with a sharp blade. You will see, among other things, a black gear-wheel on top of what looks
like a clock spring. A wire clip engages a tooth on the gear-wheel and is held in place by a 7 mm screw.
Scribe a permanent mark on the gear-wheel at the tooth where the wire clip engages (This is so you can go back
to the stock setting if need be).
This is the tricky bit: Get a good grip on the gear wheel with your fingers. Loosen the 7 mm screw and wire clip
assembly. Don't drop anything, and whatever you do, don't let go of that spring, or you may never get the car to
run correctly again!
Now, carefully unwind the gear-wheel 3 teeth counter-clockwise. This is no more than 8 or 9 mm, so be careful.
Reset the wire clip three teeth to the loose side of stock. Tighten down the 7 mm screw, replace the black cover
with a thin bead of silicone sealer and you're done.
I tried one, three, and five teeth... one didn't seem to do much, five actually reduced power. Three was just right.
Stay with three teeth because the down side of too rich a mixture will be increased emissions, and possible
damage to the O2 sensor and/or catalytic converter. YMMV.
I can report that this tweak helps solves some perceived Digifant driveability problems (assuming all else is in
order). Hesitation is reduced, throttle response is crisper, and there is mildly quicker acceleration in the lower
gears due to increased torque. Gas mileage does not appear to suffer much.
Caveat Emptor
Remember, no modifications will succeed if the Digifant system is not in good working order to begin with. In
reality, experience will show that the perceived advantage of possibly expensive modifications will quickly
disappear when you become used to the slight increase in performance afforded by the modification. In other
words, speed is addictive: The faster you go, the faster you'll want to go. The hot rodder's question has always
been "How fast can you afford to go?" - Ken's digifant page...

Re: HELP!!! with Mass Air Flow Sensor (eurospeed)
Ok I replaced the starter. Replaced the spark plugs. Repalced Spark plug wires. Replaced coil wire. Car still doesn't start. Doesn't even turn over. Can get car to start if I pop start it. It then runs like poop still. It will shut off almost right away. ANY more Ideas as to what it might be. I think I have more than one problem. WIll any computer work out of a 5 speed digifont. PLEASE HELP ME

Fix the starting / charging system first. If you have to push start it every time, it's going to make diagnossis impossible.

Re: HELP!!! with Mass Air Flow Sensor (gearhead455)
Thats what I'm trying to do. I don't know what the problem is with that. I thought that the starter was sot but thats not the problem. unless somehow by chance that the starter I put in doesn't work. Any ideas on the starting problem would be helpful.
