I know there is tons of info out there about surging idle and what not...but nothing ive read has helped me so far...so im crying out for help. I have a 88 mustang lx. All new vacuum lines. new lower and upper cobra intake. new fuel injectors, new spark plugs and wires. new fuel filter. 40 psi at fuel rails....all this was installed this past weekend and went for a ten min drive and then it wanted to stall when i would stop giving it gas. then it surges at idle. im a newbie so any info would be helpful...
