This ms45, does it refer to the ECU? Does it means that unplugging the MAF for testing will not work?

VF doesn't offer MAFless setup for these. I've been wanting that for years now... and if they ever do I will be the first one to get it lol.

On another note I had a similar issue. It turned out to be a bad MAF. I replaced the MAF and all was resolved.

Anyone here on this site is from San Antonio or near by that could help me with testing the MAF on my car? I have 3 of them already and is a bit difficult to believe that all of them are bad, but possible. If anyone can help me with the one of your car for testing purposes only, contact me to make arrangements, I'm willing to compensate in some sort of form, money wise or drinks of your choice ........TIA.

Well,an update on this thing.... I took the intake manifold to verify that all the hoses and such were correctly installed and nothing missing. Upon the removal of the manifold, I find out a small hose connection from the fire wall to the intake was really brittle and had that one replaced. Also a few other ones under there needed to be fix/relplaced and got that done. I did noticed that the shop did not installed that little check valve on that goes from the evap system to wherever it goes; the selenoid thing is right under intake runner #1, I did not ad the original one that came with the kit ( white & black) but a short trip to Napa provided one, but the color is blue on this one, I have no idea if that matter, but the guy at the store told me it should not. Got that installed and procedded to install everything back. Had the ICV cleaned and so did the TB. I really took my time to ensure that every hose/connection was secured and tight... Once I started the car, the same thing is happening, the iddle is all over the place, seems is running rich and not responding to throttle input... The one thing that this time seems different is that I actually unplugged the MAF and the car does run much better, I was actually able to drisve it for about 10 miles, at low speed, no more than 45 mph. The iddle is still hunting but the one thing I noticed is that if I press on the brakes, it stays normal and it will not bounce at all. Does any one have any idea of what can be causing this? Also I was told that on my plataform, that unplugging the MAF will not be a valid test, but the MAF in there now is brand new, barely used.. VF informed me to remove the resistors from the MAF, I wonder if I should put them back again, probably will try it out tomorrow. Any ideas will be appreciated.
