Rustoration of 1991 FOXBODY Mustang GT as a Cobra Clone

So I went back to the 19lb stock single hole injectors. No issues on the install. The idle has smoothed out and it accelerates smooth. I am getting a check engine light which I believe is a code 22 the BAP sensor. I need to test the cooling capacity of the fans but so far they seem to handle the job.

So I tried the used pro-m maf sized for the 24lb injectors that came with the car. Motor was a 94 cobra motor so these are most likely original and stock based on the valve covers, comp cam 1.7 roller rockers, plus all the castings on the motor, trans, and rear end. The radiator hoses were even dated 5/12/93. With the used maf, the car runs drives, has power sounds like an e-cam again but gets wacky. Stalls won't restart gets nutty with throttle, doesn't like the heat. Someone recently tapped on the maf and it stalled. I tried that after it stalled during a cooling system test and it changed the behavior so I am sure the maf is not happy.  (By the way, after pressure testing the cooling system, a lower rad hose was the leak) the over-heating was because the fan sensor was all the way through the rad and the tip needs to be inside for the fans to run consistently. Moved the sensor to a new spot and it stays around the "o" of normal, I might lower it down a ...

So the amazon fans didn't work out. Just not enough air flow. A friend offered to sell me an MAF for 24lb injectors. He also, by luck had a set of 2000 contour fans that came with a crack in the plastic. I had a set waiting in the amazon cart to be ordered. After a good amount of trimming and bracket creation, I mounted and wired them. I got the oe fan connectors and they cool it down nicely. I have a fan kill switch to wire in but that's future. Now the tps is acting up, if you stomp the gas and then try to start it, it would start for a second. Did base idle reset and no better. After changing the MAF I did a base idle reset and swapped the tps but I think they are both bad. The old one has dead spots and the new one isn't working well down low. I'll pick up a duralast one for $45 and it should hopefully fix it. Now with the right maf you hear the cam  and it revs out, plus you barely have to give is gas in first gear. But if I get on it, the c...
