Help with injectors...

[ForcedFirebird]

I know I need to add a 1/4 turn valve lash, that is why I am running slighty rich.
Here is a little more added info...
"33- manifold absolute pressure (map sensor signal voltage high
33- mass air flow (maf) sensor or circuit - excessive airflow indicated "
"Check the vacuum hoses from the MAP sensor. Check the electrical connections at the ECM. Replace the MAP sensor"
"Trouble Code 33 indicates that the Mass Air Flow (MAF) sensor is reporting more air is entering the engine than makes sense based on RPM and TPS. The MAF sensor produces a frequency output. The frequency varies proportionally to airflow. The ECM monitors the frequency and thus determines airflow into the engine.

The conditions for setting this code are:

* no Code 21 or 22 (TPS Error) present, and
* the air flow reported is > 40 grams per second, and
* TPS indicates < 10% throttle position, and
* the engine speed is 1400 RPM or less, and
* the above conditions exist for over 5 seconds.


Typical causes for this code include:

1) Faulty MAF-to-ECM connection
2) Exceedingly noisy spark plug wires
3) Poor routing of MAF harness (i.e. near coil packs)
4) Maladjusted TPS sensor
5) Defective MAF sensor
6) Defective ECM"

Now what may be happening is that your car might be stuck in open loop by default since that sensor has failed. You have tried changing the sensor?


Hope that helps!

Thanx again! I got home early from work today and had some light to work by (1 4' florescent in the garage isn't enough) and discovered that I hooked up the A/C vac line instead of the MAP (dumbazz), VIOLA! The car is running beautiful!
As far as the PROM is concerned, a bud is going to burn a chip for me and I discovered it's less than $100 for me to get started burning for myself (not including the chip I have to pay for from him - <$40shipped).
.
I can't thank you enough sappy and 88gtu for your input!
Hopefully I'll return the favor .

Cool beans!
