Hey Gang,
Even before the single turbo installation. I knew there is an electrical problem i have in my 1UZFE. I noticed when i drive from idle to 1800 rpm. There is a bog and then over 2k, the car fly. I always curious about this problem.
Today i just press the gas padle at 1,000 and hold it there and so on to 1,800. At 1,800 the engine rpm doesnt stay. It goes down to about 1200 and then to 1800 back and forth. Basically it would not stay at 1800. After 2000 rpm, everything is cool. The rpm jump up and down when i try to keep it at 1800.
Since its rpm dependent, do u think its the TPS? If it is TPS. Would it the primary or secondary? How about the Idle Valve Control?
