[lang=en]Hey guys!
I have a qustion about throttle pedal position, and throttle body position. The car is 2002 156 2.0 JTS. The car has no power. When I try to accelarate slowly that is ok, but when I try accelaeate hard, then is no realy power. No codes stored in ECU. The car consumes more fuel than is should, and spark plugs are black. Lot of thing is change, MAF, lambda, temperature sensor, thermostat, cat, injectors. Compression test is ok, fuel pressure is ok. My qustion is, is it normal to have so big difference between throttle pedal, and throttle body signal. The first graph from MES, and other are from csv data from MES. In some position I have realy big difference between then, up zo 30%. The pedal signal goes on, but throttle body signal is late. My mechanic dosent know exactly is this ok for this car. So, is tihis ok, or the throttle body or wiring are bad? Can you please help me?!!!

The red line is throttle pedal, and blue throttle body butterfly position.

On this can you see that pedal is pressed, and throttle body is not responding fast.

And this is difference between pedal and throttle body. Difference is up to 30%???!!! Please help!!![/lang]
