CEL still on???

Mountain out of a mole hill.

1. Disconnect battery.

2. Use some CRC Mass Air Meter cleaner from AutoZone to clean the meter. Reinstall and verify that all 4 plug wires on the harness are not frayed or the plug itself is damaged.

3. If you have a real sharp turn radius on elbow right before the meter, this will affect sampling. If you do have a sharp angle right before the meter, then find a way to mock up something to where the air is going into the meter straighter with less of an acute angle. Temporarily change it from a CAI to a RAI for testing purposes.

4. Reconnect battery

5. If you have a K&N. Do not over oil it when you recharge it.

Tookit apart and cleaned it. we shall see if it works.

Guessing this catastrophe was handled?

Have to put it through some drive cycles to know. Im crossing my fingers!

I cleaned the Maf with some carb cleaner and a Q tip two nights ago, but Cel is back. should I just take it to a performance place? whats the closest to carrollton?

I had a c&l on my 96 cobra that kept throwing a code too. everybody I took it to said my o2 sensors were messed up, so I'd change them and CEL always came back. I put my stock parts back on with a drop in k&n and never had a problem again.

[Cobraman]

Well @#!*% . I hate to spend money buying something if I don't know it's right. I only have til the first of the month to get this pos inspected or I'm gonna have to pay the ticket. I think the best thing to do is just take it somewhere.

You did what? You cleaned the MAF with carburetor cleaner? Please tell me you're joking.

sprayed it on a q tip and cleaned it. Is that something I shouldn't have done?

Carb cleaner is very harsh and will/can damage the fine wire.

This is why they make a cleaner special for MAF sensors.

Denatured alcohol works the same if not better.

Using a q tip is okay as long as you don't leave any fibers behind, because they will insulate the wire just like grime and it will throw a lean code.

What I have found that works best, use the pressure from the aerosol can to knock off the grime and let it air dry. ~5 min.

I have a scanner that reads live data, it can tell you if the MAF is giving a flawed reading.

If you are using a c&l trade it to someone for a stock housing and don't look back until you are flowing enough air to even need a bigger meter.

Goddammit kid. Didn't I say to go pick up some cleaner that's for cleaning the MAF? You're cleaning a piece of very sensitive electronic wiring, with something that's used to clean carbon off of metal. Find a stock meter from somebody and slap that on, like mentioned. You don't need a bigger meter with your mods right now. The only time you need a bigger, aftermarket meter is if you are changing out your fuel injectors.

Unless you know exactly what the reading should be at a given rpm with a given amount of airflow your live data won't do you a lot of good. If the sensor reads some complete off the wall measurement you might catch the problem. But, I only do this everyday for a living so I might be wrong.

Also, I've got a stock meter from a 98 gt with a drop in k&n I'll sell you if needed. Oh, and carb cleaner is bad, using the q-tip is not recommended but I've done it before. You have to be careful not to damage the sensor.

98 GT and 96-98 cobra PCM's aren't the same. Look at it this way, the GT has a SOHC 205hp 4.6 with 19# injectors, compared to the cobra with a 4.6 DOHC 305hp, with 24# injectors.

I was going to check for what normal voltages are suppose to be and compare. Long shot but plausable.
