2004 Toyota RAV4 Questions

I need a complete engine replacement, for my 2004 Rav4 where can I find one and who can I get to perform the work

Idles ok, push throttle down no response, then engine revs suddenly

after replacing headlamp i turned lights on and new light was not working right. i put that light in the good side to make sure it was good, it was so i put second good light in the one that went out. it would barely come on, i tested the voltage on the bad side and when i stuck point in hole 1 of three the other side headlight came on, i put new bulb back in and reattached it, i also put the good side back, turned on lights and both sides barley work, when i hit the brights the side that was good comes on bright and the one that had gone out does not power on at all. also i unplugged the big connector to the brakes to replaceheadlight, and put it back in now my brakes make an awful noise like abs is off could these two be releated, it was raining a little bit and there was heavy moisture in the air, i checked all fuses, and even put scan tool obd reader on car, no electrical problems showed up, the abs test did say master cylinder main control not working but i already figured that out. is there something i need to reset when unplugging that main connector and with my headlights could the fact i touched the bulbs numerous times and it weas raining have screwred the lights up or could i have blown a relay not a fuse.

The car starts, and idles, will drive at idle speed. No fuel disruptions, bad timing, misses nothing. But will not move any faster when pressing on gas. All the way to

door locks, ac, radio, only working is interior lights and head lights

May high beams work but my headlights don't. I checked the fuses but I'm a little confused.

is this a fair price and should the strut and swaybar be changed in pairs ?

It's difficult for it to rev. Why?

The shop used Dexron3, along with an additive, which they said would make it the equivalent of Toyota ATF4. Within a few days, I had trouble shifting gears and ended up needing a transmission rebuild. The oil express shop stated that although the wrong transmission fluid was used, they put the additive in which would have prevented any problems from occurring.
