Cant smog, car jumps and sputters on dyno. - The Ford Focus Forum

**sofreshsoclean** · 11-04-2009, 01:38 AM

I have an 01' ZTS it has a MTX75 with a torsen LSD, I also have Advance trac. TC.

the smog tech says he cant smog it. that the TC wont turn off. and the car trys to jump off the rollers and cuts Throttle and he cant maintain RPM for the test.
the TC light has been permently on for the last 2 years (since the LSD install) i thought it didn't work anymore. so i'm real suprised. before the mods I remember how drastic and harsh the TC was, it almost seamed dangerous for pulling into trafic on a right turn. But now... it doesn't seem to pull throttle at all when I spin the tires on the road, But maybe i'm spinning my tires less than I think. First gears kinda a blur now.

Should I just pull the ABS fuses like the SVT foci guys do? or could this be the LSD locking up?

He's the only smog tech who will let my car come close to his' dyno.

are there code readers that tell trans codes?

Maybe I'm missing something, why would you get a TC light from doing the diff?

I can see how TC would be an issue on the dyno if it's also reading the rear wheels though.

Fix the TC issue and you'll probably be fine.

I think my tc light has to do with, stearing angle sensor. When were doing the diff and drinking beer (natrually) someone spun my stearing wheel round and round, with the whole garage going "NOOOOO!!!!" I think the wire loop cartridge is messed up. any way.

If i pull the ABS fuses will I get an engine light?

Well I pulled fuses and it didn't throw a CEL just brake and abs lights. which don't affect smog, so to make a short story shorter... I got my focus smogged. Woo hoo!
