1G I Need Help

[90awd4g63]

Here's the deal I have a check engine code concerning the mass air.

According to a local tuner shop they said I will because its a 2g mass on a 1g car, so the ECU needs to be calibrated. Is this true, because this has just been a re-occuring problem for about a week and a half? I had no problems for 2 months.

Yes, I have checked and cleaned the mass air. No, it's not hacked. I have 550 injectors, 255 Walbro pump, and a SAFC. I do have a logger and the MAF has readings.

What should they read for one, and what else can I check to get rid of it the light? My drivability is not effected. No boost problems or fuel cut.

I've run a 2G MAS on my '90 for 10years without a CEL.

My thoughts are that either you have it wires incorrectly, one or more connections is bad (you did solder/shrink tube all connections ) or your MAS itself is faulty.

If all connections check out, disconnect the (-) terminal of the battery for 10secs+ and see if the CEL clears

yes the connections are right. There soldered, and the MAS has been on there since the last owner owned it. I was just asking cause it just started this problem. Thanks anyway. I just have to go find a 2g MAS to check it.

I got a 90 TSi AWD. Here's the problem. When I turn the ignition on I have no check engine light, but when I start the car, about 5 seconds later the check engine light comes on and stays on while driving. As soon as I turn the car off and turn it back on, no check engine light. It does the same sequence. I tried checking the code but it wont let me, seeing there is no code with the car turned on and not running. Why is it throwing a code but wont let me read it? Could it be a bad O2 sensor or something to that effect seeing the car has to be running to read certain sensors? This is really getting annoying.

What are you using to try to read the code?

I got the code read. Its the MAS, anyone got a 2g MAS they'd be willing to sell???/
