i got my true duals done about a month ago

and it ran fine for a while and then mabye 2 weeks ago i got a full take of gas and sometimes when i drive it and i drive around 2500 it feels like its clogging or something

i thought it was bad gas but ive ran all that gas out so who knows.

i have a little miss at idle i think im gonna try and change the spark plugs see how that helps.

 

Do you still have cats?

Misfires cause the engine to run excessively rich. That can foul plugs, damage the cats, load up the O2 sensors, etc.

 

If the cat was plugged it would run bad and would not get better as you reach higher rpm's. If one was plugged it and the manifolds might glow red.

 

no i do not have cats the exhaust shop took them off for me

 

oh and it does have that clogged feeling when going past 2500 too and stops when i let off the gas and give it gas again

since i dont have cats wat do u think the clogging feeling is?

 

Are you sure that its "clogging", and not just running poorly and misfiring?

 

ehh it was running pretty good and today i swapped out 3 spark plugs on the right and 2 on the left i couldnt get the rears out so its running ruff now

im gonna take it to somebody next week and have them change the rear plugs for me and see how it does then.
