Code 41 and missing all over

my 88 f150 with a 5.0 is missing bad (driving my 86 for now) pulled injectors and well the pintle caps on a lot of them are cracked really bad and some have a big pieces missing. could this cause my running lean condition. fixed my vacuum leak so code 22 is gone (thank god) but im still having a bad idle and hesitation under acceleration. it clears up after 2k rpms. anyways any insight would help. the pic isn't of my injectors but its similar to the cracking and also remember that 3 injectors have a good 1/4" missing of the cap. thanks guys. also my plugs look good so its not dumping too much fuel since they aren't fouled

Could this actually be the problem as well?

Well, what are you referring too?

The corrosion around the terminals inside and on the rotor? That looks fine and mine has been worse. I clean mine off each year and usually though, mine always seems to fire off quickly.

I just use Emory cloth and a razor to clean them.

Evan_P has a thread about that process.

i went ahead and checked out evan p's thread and i was wondering if i can use the 4 hole injectors.....seems more efficient. i will also be replacing my whinning HP fuel pump. my exhaust is loud since i have a cherry bomb on it and i cant even hear that with the pump.
