Trust me...do not go cheap on the mass flow. Mine went bad and I bought the cheapes t one I could fine. Couldn't get the check engine light off and my truck ran ok for a bit then it **** the bed. Buy a Bosch because eventually you will anyway. Also very easy DIY.

lol, damn. I was about to ask why some were dirt cheap. I guess you get what you pay for.

You can get the MAF readings with a ODBII scanner. It measures airflow gallons per minute. Cleaning a D2 MAF normally kills it.
You can unplug the MAF cable and the engine will run with default values. Do this when the engine is running badly and see if it makes any difference.

OK, so here are the CEL codes as they came up on the OBD:
There are 14 total
P0733- Gear 3 ratio incorrect
P1300- No Definition
P0303- cylinder 3 misfire
P0305- cylinder 5 misfire
P0171- Bank 1 Too Lean
P0174- Bank 2 Too Lean
P0301- cylinder 1 misfire
P0307- cylinder 7 misfire
P0300- Random Multple Misfire
P0301 again- cylinder 1 misfire
P0308- cylinder 8 misfire
P0303 again- cylinder 3 misfire
P0305 again- cylinder 5 misfire
and P0307 again- cylinder 7 misfire
I find it weird that cylinders 2 4 and 6 aren't misfiring. Any thoughts?

These codes point to a bad MAF:
P0733- Gear 3 ratio incorrect
P0171- Bank 1 Too Lean
P0174- Bank 2 Too Lean
The misfires can be bad plugs, wires, coils, sticking valves, injectors...
How old are your plugs and wires?
Do you know if the wires have been changed?
What gas are you using?

Do you have any idea why it only runs rough when the motor is cold?
I use Premium Unleaded gas.
