Do you have a breakdown of the run? How many miles are on it? Something's definitely wrong there.

I would imagine they are stock..dunno though, they are on the list.

would a vac. leak cause this? it pulls 18-19" @ idle (~900rpm in park)

I don't think a vacuum leak would cause that kind of slow down.

Dunno if this has been said yet, but is the spout connector clip together? I know it seems kinda of stupid but trying to throw out some ideas.

Take to the Ford garage and have them wipe the injectors clean. That might help. Maybe. lol

The pointer could be bent for the timing, the balancer may have spun on itself giving you a bad timing reading. You are pulling the spout when you check the timing, right?


Check your timing with another timing gun.

What elevation are you running at? Are you spinning when you launch, 2.3 is off the norm, unless you're spinning.

You may have too much oil on your K&N. Try running with just an open throttle body and see if that helps... more air, hot or otherwise is better than less air.

sounds like you are running WAY lean..borrow someone's mass air meter and see if that solves it (my stang was doing the same thing, mass air meter fixed it) check vacume leaks

up the fuel pressure to say 50psi, if it runs better (but still will run like ass) then you are running lean..go from there..what about your roller rockers.? were they installed correctly? yes a nasty vacume leak can make it run like this also..

had it on a dyno, its backfiring up top, made 198rwhp 290rwtq.

AF was good, but all over the place between 12:1-13:1, probably from the backfring, when it would break up, it was smoking a little bit...seems ignition related, I have checked the timing with 3 different lights, it runs MUCH worse at 12 than 14...backfiring wise...

Our trucks have weak valve springs and should be replaced. Mine were so worn out at 70,000 I couldn't rev it past 4600. you also need to look at the timing chain
