77 zoom zoom

I am hesitant to bust that AFM open! They are spendy, but I think that is where I need to check next. I have checked timing with timing light, could the distributor or vacuum advance be bad? I am new at this. My 63 caddy is way easier to work on!!! This fuel injection system seems so complicated but I know it has to be something easy to fix....frustrated!!! Could my fuel system be plugged? I appreciate everyone's input and will try everything you guys suggest!

No I haven't checked that yet and is a good idea! Will check tomorrow (saturday) and will get back to you...thx

It idles great but when I give it gas it cuts outs and falls flat on it's face, won't rev at all past 1500-2000 rpm. I am thinking checking contacts in the AFM is my next step?? The car sat for 8 years before I bought it and was in fine running condition...so I was told!

I have a 77 280z w/fuel injection. I have replaced the fuel pump, filter, plugs, TPS, blew out all fuel lines, new injectors, new fuel hoses, cleaned out fuel tank. It idles great but bogs out when give it gas. I cannot figure this thing out! It is not drivable but idles killer. Does anyone have a clue what it could be??? I am at my wits end with this car!!! HELP
