I replaced the injectors and the car was running fantastically. Then occasionally it would spit and sputter on acceleration, but would go away. Now I can not accelerate without it bogging down. Went through and replaced TPS, Coolant sensor, MAF with no help to symptoms. The check engine light stopped working on me, I have replaced a burned out light bulb. but now there is no voltage to the check engine light circuit. All other lights on the information console work. I have read back on some posts that make suggestions of possible ECM failure.
One other thing to mention is it will start and Idle but when it hits closed loop I hear air coming from air intake and catylitic converter.
Possible Diverter valve problems??
Help
Thanks in advance
