no year told, at all. you blew out fuses the instuctions told you to first pull main battery 12vdc NEG LUG FIRST AND DID NOT? OR WIRED IT UP WRONG. LEARN TO CHECK CALL CAB FUSE BOXES AND ALL ENGINE BAY TOO. the operators guide in the glove box in hand chapter fuses covers all that. lost it? it is free , in USA are you?

check fuses scan the PCM bingo? tails is old name for PARKing lamps. parks can be 8 or 9 lamps, 4 corners, + and 2 per side. even some mirrors on sides. 10 lamps, area ALL out, or just rear if car has BCM and the BCM runs all that, there my be no fuse (its electronic inside BCM) and if one lamp short all lamps on that one wire all go dead unit the short is cured.)

It could be many things, but as it happened so soon after the timing belt replacement, I would ask them to come and look at it under the repair warranty. Issues like this can only be diagnosed by computer diagnosis.

I have the same annoying problem on my RC350s. It have spent hours trying to fix it but I can't find a fix!!!

Have you made sure that the fluid is full? Slow shift can also be caused by low fluid pressure

RTM https://eautorepair.net/Marketing/Default.asp most plugs have pin counts not the same and are keyed did you know that? look first then match it up. and wire colors both sides, same. always do photo on jobs this hard. or tag each pair. 1a,1b, 2a,2b and on keeping 50 cables in the head is never easy, and near deity like if can.

OXY SENSOR IS SHORTED(was)AF (named by Lexus oddly)THE FUSE BLOWS IF SHORTED DID IT? 25amps blew up?AND WHICH RELAY, EXACTLY.both p1135/55 means , B1S1 and B2S1 both front sensor heaters are dead but gee wiz with relay pulled sure they are. dead.AF heater relay runs both those 2 front O2 sensorsand if either of the 2 short. fuse marked AF heater fuse blows 25AMPSThe heaters are spec at 5 ohms so each heater uses 3amps 6 total paired, and 25amp fuse does not blow.but if the 2 heaters B1S1 and B2S1, short the fuse blows. so bad 02 front sensor. or wires to them melted or cut in halfwires on O2 , with clamps missing allow wires to touch 2000f header pipes(exhaust ) and melt and burn up, and then short.or even burn open.or put in the wrong 2 front 02 sensors or used the cheap ones$20 that are hand wired, and wired up wrong.. (done lots but not wrong yet, I'm careful) I run BOSCH only, and or OEM fitand easy to pop in, the Bosch web site has the Ecatalog to get the correct ones. from them.

You need to get the repairs to the fuel pressure regulator re-checked. Fuel from the Exhaust is a SERIOUS issue. You also need to check the gas tank as well. A leaking tank can look like a leak from the exhaust.

This sounds deeper than a fuse. If you have access to a professional scan tool, monitor the voltage of the sensor in question. If there is no movement, or choppy movement, especially upon acceleration. If there is any discrepancy, replace the sensor. If you do not have access to a professional scan tool, check for power and ground at the connector using a DMM (Digital Multimeter). Once those are verified, you will need to backprobe the connector while connected to the sensor, and verify that the signal wire is giving the proper voltage. This, unfortunately, will require a lab scope, which most people outside of a shop would not have access to. It only gets more technical from there, which will most likely require some diagnostic time at a professional shop.

The most common causes of a VSC light are a faulty accelerator pedal, faulty throttle body, faulty ABS sensors, or a faulty mass airflow sensor. You need to get an OBD scan tool and tead the codes.

Did you disconnect the battery? Did you reset the antitheft system?

routing of what no told 3000 + parts on a car , we can not guess what's wrong, or up.

You can remove the back seat and reach through to the latch from the inside.

It is located on the exhaust manifold and you will need a ratchet and a oxygen sensor socket in order to replace it.
