Very true! I've done just about everything except a fuel pressure test. I'm thinking since car sat for a few years and gas I took out was kinda Orange.
Im thinking maybe the engine is cutting out a bit due to fuel pump sock being gummed up.
I still have to put in the 02 sensors I bought
If pump turns out to be good and I put sensors in
And still not good. I'll be creating some very choice words!
I won't give up but still.
im crossing my fingers here..

 

update.. Did fuel pressure test and key on. No start pressure is at 50 when I start car it drops to 47 steady
When it's running and I unplugged vacumm to FPR it jumps up to 55 psi
So looks like fuel pump is ok
Next step is O2 sensors.
I'll update after

 

Well here I am again!
same old crap! I keep getting the PO304 code but Everytime I run it. The code comes up less and less
I put risolan ring seat in oil and a bottle of risolan detergent additive in and seems like it's working
I have less lifter noise and seems like rings are sealing good!.
I pulled the number 4 spark plug and it actually has a grey burn on it as it should!
To recap. First time I pulled the plugs all where burning light grey but number 4 cylinder was little wet probably fuel! Replacing the injectors was a good idea.
Now it's doing better
when I keep engine at around 1200 rpm's check engine light stays off and lifter noise disappears
Im hoping the more I run it the better it gets

 

Update! I've been running engine every day and I pulled #4 plug. It's burning a light grey as it should and engine sounds better,!
i ordered a new fuel pump that comes with new sediment sock!
I will change that!
I have made checks on all sensors and they ar all within specs!
So I think with new fuel pump and pre filter
This car will be like new condition running wise!
So far I have put over 300.00 in so far.
Why stop now!

 

Good to hear things are better. I hope that new pump puts this all to rest for you.

 

Thanks I'm going to get put Thursday and install it.
ill post the results

Awesome, hope it delivers the results you are wanting. Don't mind me, I'm getting my lounge chair and popcorn ready... Best of luck, fingers crossed for you bud!

 

Ok replaced fuel pump sock filter
and now car drives ok but still a little hesitation when higher rpms I drove it 6 miles round trip and it drove better than before. More power..
I still get PO304 coming up and some lifter noise from back of engine possible cylinder 4
I'm thinking that's why the misfire..
After I changed oil again I added some restore the blue stuff in can it says for engine compression
I'll drive it some more and see if it works.
