Default How to test 42lb Lucas Injectors?

Car seems to be misfiring a bit.

Need help!

Replaced plugs, wires, cleaned MAF, replaced Injector Orings.

Here is a few logs

misfire 1 and 2 are before the plug/wire change

misfire 3 is after the plug/wire change/maf cleaning.

misfire 4 - i flashed to an older tune to see if it was the tune.

do you have a cam? or just the turbo? did it do the misfiring anytime after the turbo install? have you been getting oil into your intake tract a lot?

I did a cam install and had to modify my misfire threshold tables, I do NOT believe that you need to do this as you don't have a cam, but just putting it out there.

I believe that there is oil in the intake. Stuck my fingers in there and they were black when I pulled them out, wet with a bit of oil.

Think im going to buy a pill for the turbo oil feed, i beleive it may be pumpin to much oil into the turbo.

Also, I never had a misfire until 2 weeks ago. So maybe the oil has finally began to build up in the intake?

ok...a bit of oil versus your fingers coming out black.... define more please. lol.

there should be a thin layer there...regardless of what you do that will probably happen, but to stick your fingers in there and they come out BLACK and coated... thats not good
