i just bought a 99 ex-cop crown vic, and im having some problems with
her. she lags when i step on the gas like the fuel injectors arent
working....i took it to get tuned-up and all and then she was running
fine and its kinda startin all over again. they replaced a few coils,
sparkplugs which supposed to be related to the problem. anyway, i
really want to get her running like she suppose to, wit some balls!
does anyone know what might be the problem?
