i have just redone most of my turbo 2 fuel system...injector gromets, new lines up to the firewall new intake gaskets. i have also done emissions removal and checked my coils and they are all within spec. im fairly sure that there is no vaccume leaks in the system. i have a problem on aceleration...when i hit the gas the car boggs and backfires. i was thinking most likley a fuel pump problem. can anyone shed some light on this problem.
