Definitely plugs... Posted by turrbo [Email] ![]() ![]() ![]() In Reply to: Re: Just illegal in many states...which is quite a problem., Steve, Sun, 10 Jul 2005 19:44:33 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I'd have the fuel system and injectors professionally cleaned. Air filter or fuel filter could be suspects. And of course, check for vacuum leaks.
Could also be that your DI is starting to go...unless you've replaced it recently. I'd even say to check the adjustment of the wastegate to see if your turbo is boosting correctly. I assume you're still a LPT with no boost gauge, so you'd have no way of knowing what the boost is...This is assuming you're in the US with a US spec car.
I'd even go so far as to say that a sensor could be reading wrong (throwing off the mixture) before suggesting to cut out the cat. The cat doesn't seem to be a problem with the 9k, but then again anything can happen. I do believe that a good shop can test the cat to see how its flowing.
But I'm thinking that good NGK plugs properly gapped and a good fuel system cleaning will solve your problems.
