the wideband is an AEM 30-4100 gauge-type UEGO controller with the bosch LSU3.2 sensor. I believe i have to remove it to calibrate it to see if it bad or just slow. i can hook the sensor into the computer. there is a 0-5v analog output. there is also a serial output for data logging. would i be better off using the analog output on the wideband to make sure that the stock narrowband sensor is not bad. i mean why buy a part if i dont need it. Knock sensors should give a code if its detecting knock correct? AFM Bad? Cant find no vacuum leaks but i heard alot of people talking about the vsv's under the intake manifold go bad and cause a vacuum leak. i saw somewhere on the internet how to test the afm meter with the ossciliscope. however you spell that. i believe it is a square wave. thats all i know. caps dont look like they are bad. any specific ones that would leak. i mean you could tell if they were leaking by looking at the board.
