My sc400 has been very sluggish over the past couple weeks. If i give it gas, it will accelerate but very slow and sometimes if i mash the gas, let off and mash again it still won't respond. It used to happen once or twice a day. But it's been happening a lot lately. I put it in the shop and of course it didn't act sluggish for the two days it was there. I recently replaced my fuel injectors. Engine and tranny are running strong. When I first got the car the cats were clogged and my uncle cleaned them out before I picked it up. Do you think they could be clogged again? Should I still drive it? thanks

 

moved to proper forum.

 

my bad thanks

 

I wouldn't rule it out-- Maybe a fuel filter change while you're at it--

Get somebody to pull your codes too-- could help narrow it down--

 

its not throwing any codes though

 

Just because the CEL isn't on doesn't mean you can't pull any codes -- It sounds like you may know that but I'm just checking--

Do this-- unbolt the flanges just behind the cats and look up in there-- you'll see real quick if there's crap in there-- let the system hang by some mechanics wire and drive it about 100m and see if it pulls hard as it is loud-- if so-- your exh system is full of cat-blown-chunks--

If so its time to fab a new center section like I did-- this is one of the reasons I did that --
