Would a clogged muffler cause a problem in acceleration? Im pretty sure the engine still runs fine, it just has slow acceleration, I can get the truck going 160-170 on flat (It is the v6 so it has little power.) But it has problems accelerating. I get going to 100km's per hour in about 15-17 seconds (60 miles) So I am wondering if a clogged muffler would do this, My cat converter was clogged previously, I removed it fixed my idle issue. But Acceleration is very slow. I would like to fix it. Should I strait pipe it or just buy a new exhaust.

do a tune up.... no i dont think you have a clogged muffler...

 

What should i Do in the tune up?

 

clean tb intake iac plugs wires cap clean/change injectors air filter fuel filter pvc valve

 

also maybe think bout synthetic oil change...not sure if it'll make much difference..cause im pretty sure its damn hard to clog a muffler

 

How do you clean out the PCV Valve?

 

cut the cat off

 

Why cut off the new cat???

 

I wouldnt clean the PCV Valve. I'd replace it, cleaning it just opens it up for a little while then it will clog up again shortly anyway. Easier replacin it.

 

Just replace that hose? or the thing on the end connecting to the cam.
