20 Most Recent 2007 Lexus IS 250 Questions & Answers


Ok, i find it very hard to believe that this car came from the factory with an unset valve assembly and, i don't believe that it would have been delivered to the dealership with some bad injectors. I agree. this car smells like lemon pie and i would seriously think about practicing your states lemon laws. This car was dead on arrival unfortunately. there is nothing normal about a ticking sound coming form under the hood of a new car. I work on Lexus's and I've never herd any kind of ticking that was considered to be normal. Your intuitions are correct. i would return this vehicle immediately. I must say, if the ticking sound is very low range and is coming from the injector areas, this is normal but, if its very noticeable, its not.

Please rate and god bless.

That code has zero to do with the transmission issue. You have a mechanical failure in the tranny most likely, but have the TCM module scanned first before doing any parts replacement. P0171 is most likely an O2 sensor issue, it is indicating lean fuel.

read the owners manual on the operation of a tiptronic box. It will probably state that the manual selection of the box is for keeping the gear box in set gears to prevent unnecessary gear changing. So when going down hill select a gear manually and that will use the engine braking capability instead of up shifting as the rpms increase
It is fun to use the tiptronic as a manual box but that is not the real purpose of the transmission design.. IT is to lock the transmission into certain gears to prevent unnecessary up and down shifting of the transmission

Did you try the battery connections. Make sure they are on correctly.

spray everything with a water dispersant (wd-40 or CRC) . spray into connections --in distributor cap and on plugs and leads . You have a water contamination problem from the water in the engine bay.
