Ok, will do the last steps today then. Thanks!

Feels great. Engine feels more 'alive'. Definitely more pep and power. I didn't get the oscillation at cold idle this morning, but it did throw a CEL after driving for a few minutes. Should I disconnect the battery for a while and then do the last few steps?

i think theyre saying to just live with the CEL for maybe a day or two and just let the ECU adapt. I would give that a shot.

MGargano · 04-14-2009, 06:25 PM

I have the battery disconnected now... will run through the steps in a few hours...

MGargano · 04-14-2009, 09:26 PM

Did step five 2 1/2 times and the oscillation is gone. CEL hasn't come back either. Will check again tomorrow morning when cold starting. Revving up to 4,500 in neutral for 5 minutes was probably the hardest part... poor little car!

gwasabi · 04-14-2009, 11:20 PM

MGargano · 04-15-2009, 12:58 AM

lol it'll all be worth it if this keeps the CEL and oscillation away

Ouch... Sounds painful!

MGargano · 04-15-2009, 06:29 PM

Got some light oscillation a few times today, so I did step 5 again. Think I should just drive it hard for a few days?

gwasabi · 04-15-2009, 06:35 PM

When do you get the oscillations? while driving or while in idle?

MGargano · 04-15-2009, 06:40 PM

At start-up when it's cold it oscillates 4-5 times and then stays around 3k for about 30 seconds, then calms down to normal. I get oscillations sometimes when driving too.
