[s-cars] I want my MPG

[Theodore Chen]

i got a surprising phone call last friday: my car passed smog.  the tech wasn't around when i picked up the car, so i wasn't able to find out what he did to get it to pass.  my car had been blowing about 125 ppm HC at 2500 rpm (the limit is 120) and passing the other tests, so it was right on the edge.  the latest test results showed 117 ppm HC at 2500 rpm - so it just barely passed, and that was probably within the range of normal variation.

it's clear to me that i still have to find out where the extra HC is coming from.  i haven't gotten a chance to warm up the car and put it on VAG-COM yet, but that's on the agenda for this week.  meanwhile, i discovered my car has a new problem: misfiring badly at 4000+ rpm, or under high boost, and it happens every time.  i looked at the shop report and noticed that the new spark plugs that the shop installed were $4 each.  at that price, they're definitely not the F5DP0R.  so i need to get new plugs.  i don't think the old ones had that many miles on them, but fresh plugs wouldn't be a bad idea anyway, since i had started getting occasional misfires.  i'm debating whether to do the ignition coil conversion, too, but i guess i'll change the plugs first and see what happens.

Mark:  I know you suggested the temp sensor before.  That is why I made my earlier post,
regarding the location and function of the G62 temp sensor:

I think that your temp sensor suggestion was an excellent one and that
Teddy should pursue (sp?) that one over all others (at least initially).
