Well I pulled a code 34 today from my car which would be good reason why my car is stalling and missing. Code 34 is

 

CODE 34

Trouble Code 34 indicates that the Manifold Absolute Pressure (MAP) sensor is detecting unusually high vacuum in the manifold. Code 34 will get set when:

* Engine RPM less than 700.

* Manifold pressure reading less than 13 kPa.

* Conditions met for .22 second.

OR

* Engine RPM greater than 700.

* Throttle angle over 20%.

* Manifold pressure less than 13 kPa.

* Conditions met for .22 second.

Possible causes include:

1. Faulty MAP-to-ECM connection

2. Defective MAP sensor

3. Defective ECM

 

 

 

I'm wondering what would cause the high vacum? Also my car being an 88 with the 2.8, i didn't think it had a MAP, but rather a MAF. I'm atlost as to what my problem might be. Any help is appreciated. Thanks!
