ok some good advice lads thanks but i need to know if our car feels powerful after servicing at lexus?

Does your car drive like a 2 liter straight 6 should and feel torquey and kick you into the seat at 4500revs? or does it drive like a sluggish 1 litre that people make them out to be?

hi, that is normal, the radiator sucks the water out of the coolant bottle first when its loosing coolant from the system, is your drivers side foot well wet? or did you notice a strange smell in the car lately? if your heater matrix is leaking you will notice these signs. I just did my heater matrix, i just cut the 2 pipes going the matrix and the joined the new matrix on there with rubber hoses and clips. It saves alot of time and you dont have to take the dash out

@sjrainsford ok thanks for checking, ill leave the throttle body alone then. I know theres no CEL on but i did a diagnostic check on it anyway, with the car at idle these are some of the readings that came up; engine load percentage 34.5% map 33kPa long term fuel trim sensor 1 0.8% long term fuel trim sensor 2 3.1% RPM 650 Intake air temp 33 deg C Spark advance 7.5 to 9.5 deg does any of this seem wrong to anyone? the spark advance maybe? and engine load?

Thanks for the quick replies, @clifton 94 Good suggestion but i forgot to mention i have already checked the cam timing. @matt-c thanks for the reply matt , i sounds exaclty like you described except my pedal dosent feel any stiffer. Could some one check one thing on there car for me, if you turn the ignition on in my car and press the accelerator you can hear a bussing sound coming from the throttle body and then when you turn the ignition off again you can hear a little ratling sound coming from the trottle body, i just want to know if this is normal? I think maybe the next step is to try a new throttle body

Hi, I bought an is200 6weeks ago and was very happy until a few weeks later it lost power. The car first lost the top end kick, then a week or 2 later it lost some of the midrange, it runs perfect no misfire, noises or anything (only slight bussing noise out of the throttle body when the ignition is on, is this normal?), theres no lights on the dash and it starts fine. I am a mechanic myself and have tried almost everything including; spark plugs, i cleaned the air filter, asis manifold valve is opening, cleaned throttle body, the throttle body is opening fully with the pedal to the floor, vvti solenoid is working and cam gear, i took out the 2 front lamda sensors and drove the car to see if the exhaust was blocked, i reset the ecu, i checked the petrol flow in the fuel line, does anybody know the voltages that would be going to the vvti solenoid? ive checked this at tick over and they seem very low at around 0.25 volts does anyone have any idea what it could be because im out of ideas
