I was told that when you replace the engine on a 2001 Lexus, you also have to change out all of the wiring...someone is trying to talk me out of buying this car, putting a used engine in it, then re-selling. What do you say?

i was driving down the road just got off work and was going about 50mph, and reduce power message came up and i could only got 25 to 30 mhp hour. i pulled over and turned off the truck. then turned it on and it was fine. what's wrong?

The truck goes through spells where it acts like there is no gas (it does have gas). Error codes say there is low readings on camshaft/crankshaft Position sensors. I have already replaced the crankshaft sensor a few years ago and also replaced the fuel pump 2 years ago. I'm gambling on the camshaft sensor this time but can't find it

Car overheats frequently.

Is my engine shot

I have a 2001 Hyundai Santa Fe. For the last year or so there has been a problem with the radio cutting out and the lights (both dash and headlight, clock, etc.) dimming when the radio cuts out. This ONLY happens when the air conditioning is running. And it doesn’t happen all the time. Sometimes it doesn’t happen at all, and the next time I drive with the air on it does. I had the alternator replaced last Friday, and am still having the same problem, only now sometimes the ABS and TSB indicator lights illuminate at the same time as the radio cutting out and the lights dimming. Again, this ONLY happens when the air is running.

When the air isn’t running, I have noticed that when I turn on a blinker, or have the lights on, the clock sometimes seems to dim. When the blinker is on, it dims in time with the blinker on and off.

car will not start without it

I turn the engine off, then restart; It will work fine,until the next occurance.

Or do I have to replace entire power steering rack. I put fluid in at least twice per week. A mechanic looked and said I need to replace rack.
