Ok. First off, let me just say thanks to all the folks here who contribute to this community! What a wealth of information! You all seem so helpful. You're information on here has gotten many issues with my LS resolved!!
Like my title says, I almost have my LS resurrected.
2003 LS Base Model 3.0 V6
I have done the following to it:
Changed VCGs
Changed coils and plugs
Changed intake manifold gaskets
Changed IMT valve o-rings
Changed a few vacuum hoses
It's now running like a champ with one exception. When I start it on a cold morning, it will not idle correctly. It spits and sputters. Low idle speed I assume. I have read that bad coils will destroy cats and yes, the car was driven a lot with bad coils. Ex-wife drove it a whole season like that. I have cleared all misfire codes with the coil change. I only have P0420 and P0430 now. I know what these codes are, but my question is, would bad cats cause it to idle like this when it is cold? Since all the changes I have gotten a CEL twice, but it goes off. Seems to only come on when I drive a long distance.
Any advice would be greatly appreciated! You guys are the best!
