Thread: Engine stuttering on hard acceleration

Is it throwing any codes?
If it is check on here to see what it is:
OBD-2 V6 FWD Diagnostic Troube Codes

Or go to an autoparts store to get it scaned.
Let us know if you find the problem.

Wouldn't checking the plugs be easier? Lots of people crack their plugs while installing them.

It isn't throwing any codes. So it's not the O2 sensor. I am going to check the plugs first and then see if anything is cracked.

Hey again. I am still having the problem with my car although there now is a sound coming from my exhaust when I accelerate that sounds like change in a coffee can, making me think the honeycomb in the cat came lose. I checked the plugs and they are fine. I assumed they were too because during a slow acceleration up to the high RPMs, there was no stutter. There would be the stutter under heavy load no matter the speed of acceleration or just all the time if it was the plugs. What I am curious about is with OBD-2, which cat can I buy? Magnaflow has converters that are universal and around 67 bucks but they state they are OBD-2 compliant. I'm looking at the part number, 99306HM, and I am curious as to whether I can buy that and just have it welded it. That would be awesome and save me some money. Let me know what you all think.

On Magnaflow's website, they show this converter as being the correct one, and I called them and said their universal converters are all OBDII Compliant.
