hi all. on some days when i get up to go to school or anytime when i start my car the cel flashes 4 times and then the engine revs to about 1.5k and will hold untill i put the engine under load. im wondering if anyone knows what that means. my guess is a bad tps but i dont want to spend the money w/o knowing. thanks

Unplug the tps before starting and see what happens....If it does the same then try pulling the IAC

Were you playing with the DTC connector recently. I ask because if you left a jumper on between the self test input and pin 2 on the larger connector the CEL will flash 4 times when the ignition is turned on.

This post by you indicates you have a reader. What did I miss?

This link should help you with checking the codes without a reader.

i checked the codes and found the following... key on engine off, 552-secondary air injection bypass (airb) circuit failure/ 553- secondary air injection diverter circuit failure/ 558- egr vacuum regulator circuit failure/ got all of those 2 times/////then the memory with key on engine off, 332-insufficient egr valve opening detected/ got that one 2 times/////////// key on engine running, 172- heated Oxygen sensor indicates lean condition right side (memory)/ 332-insufficient egr opening detected (memory)//////////////////// what does all of this mean? i know that the egr isn't opening properly. however that's all i got from this.
