Default car running rough sometimes, help inside please---problem solved

i have no codes, it used to thro p0135 and p0155 for for both 02 heater circuits. but that went away.

It almost feels like i have clogged cats, but i have an ORY lol

When i press the gas pedal, it feels like the engine is struggling accross the power band, but only very slightly, kinda also feels like when your auto trans clutch packs are going out, but ima 6 speed lol2



Im going to order new 02s and new plugs, currently have tr6 for about 30k on them, i KNOW i need to change them. And as far as the 02s, they have 96xxx on them and i know the car has seen pig rich conditions and i may have an exhaust leak at the collector causing fresh air to hit the 02s
could it be the fuel filter? never changed that b4, i guess ima order a new fuel filter also.


what else could it be besides the plugs and 02s?
could a broken spring cause this? i have patriot golds .660 lift springs with about 30k on them. My cam has a lift of .598 and i have hardened pushrods so i dont think the springs are an issue since the are not maxed out and i dont have any valve float




my rear end is fine, my trans is fine both, have recently changed fluids, my clutch is fine(for the most part, lol ls7 clutch doesnt like back to back runs at the drag strip)

Gil 30k on your plugs? Dude I do mine every year, and they look like they have had a good life when I check them lol.

I agree check fuel pressure, it doesn't hurt to change the fuel filter anyways.

Maybe it's in your head gil, Your thinking your car is faster than it really is and that "struggle" feeling is your engine struggling to move your car due to lack of power lol jk.

it needs to be logged to really see whats up..... it could have a dead o2 and sometimes the computer will dump fuel in an attempt to get the millivolts up.... there are alot of things that could be going on
