So i just got the Car. Was runnin great went to mechanic did full tue up plus more. spent 600 big ones (he really took) but any ways today i got on it alittle and it started to Bog out.

Meaning i hit the gas it takes off and then the RPMS drop and rev again. And as it goes itnto to second it red lines stays there then drops into second at a low rev even though i have the pedal to the floor. Any ideas what this is?

Also i get a ticking noise i believe is from the catalitic but it happens all the time even when the car is running. not sure what that is and dont know if its related

Please give me some feed back. Thanxs guys

You should have the computer checked for trouble codes. Sounds like you are going into limp mode when a certain condition is present. Did the mechanic do everything correctly? Did they do the ignition system? It's is too difficult to say exactly what your problem is. It could be anything from a loose vacuum line to a bad oxygen sensor - (they should be replaced at around 100k) to even a torque converter problem.

Need to add more information but if the problem wasn’t there before the tune up you should take it back. It can be simple as TRAC (if the car has one) malfunctioning because of loose cable, disconnected hose etc.

You could also AIM our resident Lexus Tech--JPI. It almost sounds like too-much fuel is being forced into chamber, and then dropped. From what Moderator VMF is saying, you can get a free code reading at Autozone.

did they replace the timing belt at the tune up? if he replaced the belt incorrectly (in other words if he missed the correct cog) it could cause a severe driveability problem

BTW, the ticking noise is just the heat sheilds. It is normal. Unless you take them off. Then you shouldn't hear it any more.
