I replaced the fuel filter in an SUV last week. The next day, it ran fine. Then later I performed a trans service (removed fluid with a trans line machine, drained pan, & then replaced trans filter, then replaced fluid). To be able to access the trans line, I removed the airbox and intake. I replaced all this. Then, I drove it and noticed that it was idling low around 400 RPMs and drove rough around 1,500 RPMs. At 40 mph, twice it stalled out after deceleration, when it started idling. Can you tell me what the problem is? Thanks.
