    I have had a 97 gtp for about 4 years almost 91,000 miles on it, have done a tune up, put a new supercharger, cps, and icm on it and it was running fine, i gutted the cat, replaced the resignater with a glass pack and removed the mufflers. Now while im driveing it feels like it cuts out nd right back in but its not all the time, we have a motis at our shop and that told me the 2 codes were for the mass air flow sensor and the left bank running lean, a guy i work with told me he thinks there is a chance the fuel pump is going bad so we put the pressure tester on and it stayed at about 40 when it was running good when it was running bad it stayed right between 38 and 40psi i dont really have the money right now to just put a mass air flow sensor on and have it not fix the problem i was hoping somebody might have some ideas any help would be greatly appreciated im not much of a mechanic but i should be able to answer any questions you need me to

    Thanks

    instead of replacing the MAF i would suggest buying some MAF cleaner and cleaning it.

    IIRC your code about being lean is a common code if you have a vac leak caused by a leaking LIM. Try spraying carb cleaner around the LIM and see if you get a spike in rpm's

    Have you ever replaced your LIM gaskets??? If you are getting a spike in RPM's then you have a leak somewhere near there.

    FWIW there is no left bank. You only have one O2 sensor that is in the combined exhaust stream. Bank 1 on our cars is the one exhaust pipe. Bank 2 is typically in a V8 where you'd have seperate exhaust and a second O2.
    I drink..so consider that when reading my posts.
