For the last 4 months me 86 stang has been acting weird. First sum times when it sits and idle it won't hold it the idle will get lower and lower intil it dies out. Also when im driving when open the throttle all the way it will fill like I lost power . And when I put it in high like 3rd and crusie it well just start jurkin outa nowhere. What could this be i already changed my tps its brand new and cleaned my MAF .So could it be that i need a new distrubter cap or a new Idle control sensor thats my guess.

Time to do koeo and koer tests. Pull the codes.

how do i pull the codes

tmajikman

either buy a obd1 scanner or use the paper clip trick... Do a search for it on the site. I have the scanner so I never needed to learn how to do the paper clip trick.

i'd say its your fuel pump

drhoward

you might need new johnson rods

x2 on fuel could possibly be a fault fpr

drhoward, i doubt its the johnson rods, i believe they changed that when the replaced the horn fluid

IM running autolite premium plugs. couldn't be the fuel filter or the fuel pump those are both brand new . If it was the Fuel presseure reg what symptons would it be ?

What year? I would suggest trying just the basic autolite 25's gap them around .050. They will cost you around 12 bucks and might fix your problem. Autolite premiums are platinum and our ignitions systems aren't meant to run them...get the cheap ones, you wont regret it.
