Well shes up and running
Got the car running this weekend, ill get a video up soon.
I got a hold of some 24lbs injectors with matching pro m coldair and maf. The only thing hats wrong is at WOT it seems to want to buck, and sometime it surges and dies. Iv check for vac leaks and all, but during the build my timing pointer got bent so its not right on, ill be putting one on this week and timing correctly, Wha else should i check

yeah stock fuel pump!!!! I have to order my shrader valve adapter to my fuel pressure tester so i can check that.. I ran the car with the 19lbs and i remeber the idle thing was the same but i never went WOT with those

does ur pro-m meter have the screen? i assume you have the typical cold air kit like a BBK. i copied this right from promracing.com if you run the stock box you dont need the special calibration and screen.
"The use of an elbow causes the air to "roll" as it comes around the turn. This rolling air creates pockets of turbulence that pass by the Mass Air Flow sensing element. This turbulent air creates an inaccurate voltage output, which is interpreted by the PCM (engine computer), as an inaccurate amount of intake air. Other mass air meter manufacturers have attempted to solve this problem through "Cold Air" calibrations, but the fact is, there are too many variables for that method to be consistently effective. Different elbows with different shapes will cause different levels of turbulence. The air screen solves this problem. As the turbulent air passes through the screen, the air is "smoothed", eliminating the turbulence. This allows the Mass Air Flow meter to generate an accurate voltage signal to the PCM based upon an accurate measurement of the air mass passing through it."

No theres no screen, its a black plastic mold that goes to the maf sensor. The set up i thinks for a sn95 cause the filter bolts to the maf housing and the bracet isnt for a fox!!! thanks for the info

I Have been having the same issue for the last 2 years on and off and I have a Pro M MAF....hmmm, wonder if there is a connection. I always get a code 66 when it starts acting up.
OP, have you pulled your codes?

I took the fuel filter off and blew it out and cleaned it. I could see a light rust color, reinstalled and not at WOT is fine but it still idles surges sometimes. I pulled codes and i left them in the garage, i know there was 44, and 91. \\Im going to get an new filter tommarrow and run some sea foam through it. Any other suggeaton i should look for???
