2006 honda accord 2.4 4 cylinder sedan.
Just replaced the MAP and MAF sensor, and both front and rear oxygen sensors a day or two ago. I have an aftermarket cold air intake, but never had any problems until a few days ago. Did a oil change today, the oil was very dark for being relatively changed, put in a new filter, high quality oil. Did a coolant and tranny flush. Put brand new top of the line spark plugs in today.
The past few weeks I’ve been using seafoams motor treatment, about one can per full tank, it actually seemed to help. I wonder if I started to put too much in. I’ve now stopped and am and only putting gas in.
With all of this in mind, the car will be fine when I’m idling in drive, but if I try to give it too much gas it stalls out. If I slowly press on the pedal it takes off fine, but I’m noticing something off about the shifting. After the mechanic replaced the oxygen sensors a code came up about one of my tranny transmission solenoids being off. I wonder if all the oxygen and bad fuel ratio stuff had anything to do with that. All my oil and tranny and coolant levels are fine, no leaks. In fact the shifting seems mostly fine, Its relatively smooth once the car gets going.
I notice the shifting is a little slower, like its not getting enough gas, idling issues, it reminds me of when my map sensor was temporarily/partially off as I drove to get a new one. I wonder if it isn’t correctly placed on.
My theory is the map sensor is placed on at the wrong angle, or its something with fuel getting to the engine, fuel pump going, or a tranny issue? Any ideas? Suggestions before I have the mechanic diagnose it? Thanks.
