  1. Thanks Mark! Do you work at Lexus dealer since you got this info :winky: A very good diagram / link for fault elimination. Thanks again ^_^
  2. Just an update... no luck so far After changing sparkplugs, swapping ingnition coils, moving fuel injectors the P0300, P0302 and P0305 is still haunting the car. Beginning to think of wiringharness, but have not seen any broken/loose cables. Wondering if there is an official checklist for diagnostic of this failure (EMC steady light + TRC blinking). The car is also remarkable slow when driving int the morning in cold weather until the engine get's warmed up. But of course this may be a separate issue with the car.
  3. This Code reader does not work on the IS200. I've bought one and it can't link up the the IS diagnostic....
  4. Have swapped around the fuel injectors tonight, will be interessting tomorrow to see if the misfire changes cylinder...
  5. Thanks for the added info TG. I did not know that pre-cat breakups was common on cars that was moded with TTE superchargers. The supercharger is now removed from the car. Don't know if a broken pre-cat could cause P0300 errors, thought maybe that would give different diagnostic codes, bur thin I will try to take of the exhaust an see if the precats/cat looks ok or not.
  6. Doing some googeling and found this ---> http://my.is/forums/f115/note-all-p0300-sufferers-my-misfire-saga-327372 Wondering if I'm experiencing leaking fuel injectors or faulty catalysator...
  7. Find the posts interessting. Having a 1999 is200 with EMC + TRC flashing. Noticed the precat close to the engine got red hot the other day. Could this be the reason for my engine troubles? P0300, P0302 and P0305 showing up at the diagnostic.
  8. I have a 1999 mod IS200 Sport w/automatic transmission... Same symptons as several other is200 post... running rough for a while then running ok, feeling lack of power and using a lot of fuel, engine running hot (but not showing on temperature gauge inside car).. and of course engine management lights and TRC flashing. Getting sick and tired of this problem. P0300, P0302 and P0305 are the diagnostic codes. (Multiple misfire, and misfiring on syl 2 and 5). Have changed all 6 spark plugs, and shifted the six coil packs around, reset the codes, but the engine light and trc comes back after a short while. The codes are the same P0300, P0302 and P0305 so the "problem" doesn't change sylinders, meaning that changing plugs and swapping coilpacks doesn't help. Have also cleaned the throtle body as suggested in some othe post. Wondering what to check next, too bad Lexus diagnostic isn't a little better at pinpointing the problem... of this problem, grateful for any advice..
  9. Hi it's been a long time since this thread has been active, but trying to find out of my noisy supercharger as well... It makes a ticking noise that can even be heared inside the car. It pulls fine but a little worried about the ticking noise. Will try to lubricate the belt with wd40 to see if the sound changes but it really sounds like the charger need some service...
