I have a 1982 Trans Am that I restored and love. I had it running great for about 6
months and now it has developed a really bad lag. I step on the gas and it about dies before it finally accelerates. It has dual TBI and I suspect fuel pressure. I can not find any information on the pressure the fuel pump should put out before it is regulated. The fuel pressure at the TBI is 10 psi . The system is the stock cross-fire injection system and the TPI checks out OK and I cant find a major vacuum issue, any ideas?
