Brand new air filter.

 

this is what mine did with the restricted cat, at 4-5k rpm's i lost all kinds of power and under 4k i was fine. 200 for a high flow cat fixed this.

 

Txs 4 the reply.

Replaced stock Cat with new one last week. Hopefully replacing this #3 injector tonight resolves this hesitation.

I will let you all know tomorrow.

 

Just Replaced (today) #3 Fuel Injector and problem is still not resolved. I thought for sure this would solve the issue. Still hesitates and pops under heavy acceleration and chugs, jerks hard, and almost stalls when accelerating on an incline.

Its probably one small sensor that is causing all of this.

Quick overview of all replacements in the last 3 weeks:

Catalytic Converter
Plugs
Plug wires
Fuel Filter
#3 Fuel injector
All 3 Coil Packs

Not sure what else to do.

 

Could it be the fuel pump assembly?

The fuel gauge is going haywire and I never know how much fuel I have.

Could it cause a pick up issue?

 

Check your IAC (idle air control)

Could just be bad and throwing your idle off which will kill the car.

 

I have the same magnaflow too and love it, you can usually get a used one on ebay or cragislist. I wanted a valid warranty so I got it here. Magnaflow 15713. Also some of the forum sponsors usually have a sale going on. Either way its a great exhaust system, sounds great, and very easy to install.
