I got pretty much the same thing going on. What I plan on doing...clean MAF, then replace spark plugs, and check all vacuum hoses. After that if nothing changes I will change the cops.

If that doesn't fix, I'll be at a loss.

I'm running the Torque App on my phone and can definitely tell something is up, I need to data log everything and see if something sticks out.

I did plugs, fuel filter about a month ago.. I only have 19lbs injectors but with only intake and exhaust I can't see how I'd be making them out..

Doubt your maxing them out, could be injectors are clogged or maybe fuel pump is I the way out.

I'll be data logging mine to see if anything noticeable pops out at me.

HELP! now it's not doing it.. Sat for about an hour rained and the temp outside went down 20 but I also put gass in.. My last fill up was with BP gas.. So maybe bad gass? Or fuel pump got weak when hot..

I had a similar issue an thought it was the fuel pump and turned out to be a bad coil on plug. It started bogging like that and then got worse and worse until it misfired all the time

---------- Post added at 11:55 PM ---------- Previous post was at 11:54 PM ----------

Mine would run fine until it the motor warmed up and then run like crap and bog out

How many miles are on your car? Do you regularly run it down below a quarter tank? How much fuel was in the tank when this occurred? It sounds like a fuel delivery issue...

When you said that you filled up after, I was kinda thinking that you may have been starving the pump while you were banging through the gears there Hot Rod, but nothing you said leads me to believe that. I've had similar symptoms from a weak fuel pump but it is accompanied by some bucking also. Like its running out of fuel at high RPM. Never hurts to check the fuel pressure. Tomorrow some more knowledgeable guys will chime in and get this squared away. ..

My COPs went bad at 79,000 and gave me every symptom of a fuel pump. Only occurred when gas was below a 1/4 first and then got worse. It may not be that could be a bad fuel pump also. Could be a fuel filter also. Change the cheap stuff first

This is the problem I'm having right now. I thought my fuel pump was bad and I almost ordered a fuel pump but then I went to get the code checked and they told me it was probably my cop's. I ordered them and should get them Thursday.

Ok I did some data logging today. It appears my short term fuel trim readings are way off.

First they are no where near close to each other and bank 1 seems to always run low, like 0 to -20.

I think this is giving me a false rich.

However it's not throwing any codes.

Anyone have any experience with this?

I did a little research online, I'm leaving towards a possible bad O2...Anyone else have thoughts

It's literally just the pump. It doesn't come with everything in that kit so probably like 100. I think it's 200 something new.

Edit: Actually they are 100 new and I would rather hold it since I can't get much out if it.

I drove mine for almost 5,000 miles just fine and then I started acting up again and finally misfired and bogged all the time. Shifter handle was going crazy when motor was under a load
