Ok thanks for the answer. I'm having a problem with top end I dodn't have any and I've checked fuel presure, timing 02 sensors tps act. no codes except for a code 32 which I dont think is the problem. I even switched the MAF sensor. any help would be great.
CODE: 32 (KOEO) - EVP circuit below minimum voltage. Vref missing or broken wire or bad contact in circuit. Check for 5 volts on the orange/white wire. With the sensor removed from the EGR and still connected, press the plunger and watch the voltage change on the brown/lt green wire. Check for the same results on pin 27 on the computer. Check for continuity between the wiring at the sensor and the computer. The brown/lt green wire on the sensor & pin 27 should be less than 1 ohm. The black/white wire on the sensor & pin 46 should be less than 1 ohm. The orange/white wire on the sensor & pin 26 should be less than 1 ohm.
