RICK, MY EMAIL SOFTWARE IS BAD. WOULD LIKE TO COMMUNICATE WITH YOU
ABOUT MY PROBLEM. DO YOU WORK FOR TOYOTA? DO YOU HAVE ANY INSIDE INFO
ON HOW TO FIX IT MYSELF. I WORKED IN ELECTRONICS FOR YEARS. I BELIEVE
PROBLEM IS PROGRAMMING WHICH WOULD REQUIRE NEW COMPUTER. I DONT THINK
TOYOTA WOULD REPLACE A COMPUTER AS THE SERVICE MGR SAYS THEY COST 3K.
I KNOW THESE ARE GOOD TRUCKS, BUT I DONT THINK I CAN PUT UP WITH THE
PROBLEM MUCH LONGER.I SENT YOU A LETTER BEFORE BUT MY SOFTWARE IS NOT
STABLE AND I DONT KNOW IF YOU GOT IT OR REPLIED.  
I LIKE THE QUOTES AT THE END OF YOUR MESSAGES.
DO YOU KNOW EXACTLY HOW IDLE SPEED UP ON MY TRUCK WORKS. I KNOW ON
MY VW IT JUST BYPASSES MORE AIR AROUND THE THROTTLE PLATE. IT SPEEDS
UP JUST ENOUGH TO COVER THE COMPRESSOR LOAD. I LOOKED IN THE SHOP
MANUAL ON THE TOYOTA BUT IT DID NOT TELL WHAT HARDWARE ACTUALLY IS
ACTIVATED TO SPEED IT UP. I ASSUME THE COMPUTER SENSES THE AC
COMPRESSOR TURNING ON AND IT SOME WAY SENDS MORE GAS OR MORE AIR
OR BOTH TO INJECTION SYSTEM. IF I KNOW HOW IT WORKS I MIGHT BE ABLE
TO FIX IT.
CAN YOU HELP…THANKS
