1994 lexus ls400 runs rough cold. the verdict is a faulty cap and rotor right bank and right side fuel trims were out of specs. test found that right side camshafts was out of time 1 tooth. all problems have been corrected and man is this car fun to drive. i hope i'm not out of line for asking but can anyone sell me a heater core or point me in the right direction?

 

get one at the dealer..u put an aftermarket chinese made pos ur just asking for trouble

 

thanks, but not what i wanted to hear. but i will check on one from the dealer.

 

car-part.com can help you find one. those things are a paint to get to supposedly, half the dash has to come out lol.

 

thanks puredrifter i'll check on it.

 

what are fuel trims? and how did you check them?

 

sir to be honest i have no idea what they are. what i posted is information from the repair order that i got a copy of from the mechanic who fixed my car. i am not a mechanic and i don't play one on the internet.

 

dang, cuz my moms 94 does the same thing rough when cold but smooths out as it warms up....does anyone else know how to check fuel trims?
