pmas for 30# injector help

[jromeo]

I just installed my used 30# injectors and new pmas air meter and now the car runs like its on 7 cylinders. so I put my pro m mas air back on and the car runs smooth as long as your giving it a little gas, it will die if you don't ,but it's calibrated for 24# injectors. At first I thought one of the injectors didn't work, but they work fine with the pro-m . has anybody have any problems with the pmas meters?

Has to be a miscalibration on the PMAS. Be careful of those used injectors. Not sure where you got them from, but the 19lb/hr injectors for a truck are actually color coded red. People will pull them off a truck assuming they are 30lb/hr injectors, and sell them as such.

I checked the part # on the side of the injectors and they came up as 30's.

Well good, then you've narrowed it down to a miscalibration of the PMAS.

well thanks for the help, i'll send it back.Maybe i'll get another pro-m.

I think PMAS is the new Pro-M. Pro-M went out of business, and the old employees from Pro-M started PMAS. I've never heard any problems from their MAFs, but there is a first time for everything.

well I put it back on the car just to see what happens and it works now.
drove the car all day today with no problems, so I made an appointment to get the car tuned this tuesday.

Maybe those injectors just needed a little fuel ran through them if they had been sitting around for some time?
