New knock sensor, now no power
I have a 1990 Toyota 4Runner with the v6 (the v6 where the knock sensor is under the intake manifold). The computer was throwing out a code of a malfunctioning knock sensor. So I replaced the sensor. The timing belt was not removed, so timing was not changed. Took me all day (8 hours). Finally got everything back together. Started right up. However, it has a rough idle, absolutely no power, can’t get the car to get past 35-40 mph. The RPM's go up to 4-5k but the car acts like the parking brake is on. The computer does not have any codes any more. Spend hours following vacuum hoses and electrical plugs, to find everything hooked up correctly. I unplug the throttle position sensor and the engine idle speeds up. I am so frustrated, can any one help please! The engine is not running hot, and the EGR valve seems to be hooked up right. If the computer is not throwing out a code, what could it be? PLEASE HELP!
