98 GT that sat for couple of months. 170000 miles. Had a miss and I replaced plugs and wires. It got better but still has a slight miss and mechanic could not find anything in the computer and suggested running injector cleaner thru it, which I am. Can anyone tell me what the STOCK flow pressure is for the fuel injectors. I may pull injectors and take them to be cleaned, but I am also thinking of changing the injectors and the fuel rails. Summit Racing has injector pressure from 19 lbs. on up. How far can I go on the injector pressure and how will the above effect everything?



Thanks

 

the only thing i can tell ya is that i work on planes, when we check injectors, if shop air doesnt fix the problem, then we replace em. so inspect em and go from there

 

Some of the carb shops have a machine that injects cleaner fluid thru the the injector in high presure pulses something like a waterpik(teeth). I've got a couple of friends who had good luck with this.

Thanks
