My 96 stang is loading up 6 plugs the thing that gets me is the #1 and #6 plug look like new,the car runs terrible no power,missing,etc. Ive replaced the wires,coils,plugs,injector seals,f.p.r. also with the car running with a screwdriver to my ear i can hear the injectors tapping=is it possible those two injectors are clogged=any suggestions? 5.0 stroker comp cams pi heads 60lb. injectors d1sc
What kind of plugs are you using? I had to switch to NGK ridiums because three sets of plugs(autolite,(2)ford)would not fire under boost. To check the injector plug the clip off (while running)and see if anything changes.
I'm running autolite 764's i was running ngk's and it was doing the same thing.I tried you're suggestion and pulled the plugs to #1 and #6 fuel injectors and the idle didn't change at all. With the car running and the injectors plugged in i can hear them clicking with a screwdriver. I'm guessing either there clogged or getting a bad signal possibly from a bad crank or cam sensor? Where should i go from here? I appreciate all suggestions and advice.
If it didn't change then they are bad. But check with a volt meter the volts coming from the signal wire (plugs on injector).
I borrowed a igniton tester that goes between the wire and plug and those 2 cylinders are getting no spark,ive triple checked the firing order replaced the wires,coils. Any ideas on what could cause this bad computer,msd?
