Svo feels slow

Ok so here's the problem.

Car doesn't pull as hard as it use to

I checked compression, haven't checked the fuel pressure but I will today.

The car also makes a rapid backfiring sound when i let of the gas really quick.

I already ran codes even made a video but my phone has a arc and tn video file so I can't upload it to youtube

codes are:

25:knock sensor-
34:EGR Valve-cleaned
41:EGO Lean-changed o2
77:Operator error-didn't wot

I cleaned the egr with carb cleaner didn't get rid of the code changed o2 nothing...new knock sensor(guessing it has to do with code 77)

I even disconnected the battery for 30secs didn't fix

any idea i sprayed almost the entire motor with carb cleaner no change in idle. vacuum is at 16hg use to run really good when the vacuum was lower. Also on a side note I had my spout wire rip off and didn't know why the car acted funny. I figured it out and spliced them together ... could this have messed up my ignition timing cause if im not mistaken the dizzy would have to be rotated in order to change ignition timing. any help would really help out thanks.

How many miles/months has it been since you changed the plug wires?

I have changed out cap, rotor, plugs, wires, pcv couple months back. fuel filter and pump about a year ago... turns outs that when I rechecked the motor after it was running for a good while. the vacuum leak was more noticeable it was coming from the last injector. I'm guessing its the o-ring but now I'm thinking if i should just swap everything over while I' m at it.(35lb,la3) ;D

[Stinger]

Do you have any data to back up your thoughts that it doesn't pull as hard as it used to? How much power is it down from before (10%?)?

[RoLo]

No data just butt dyno but im guessing like 25%.

[Stinger]

I'd check the cam timing and if it is perfect, check ignition timing.

The connector clip inside the fuel line broke and was spilling gas and the 4th fuel injector wasn't sitting right... guess it was leaning it out but I put the pintle and o-rings on the 35lb and im going to run them on my stock intake with the la3. Thanks for the help Stinger btw might buy your 3inch dp sometime next week.
