Ok so this has been happening for a while now, maybe a month or so. When I accelerate from a stop, the car revs faster and higher than normal, then the revs bog, and my car shifts. Also the car seems to not want to shift until it reaches a certain speed. And also, when I put the car into drive, its takes a few seconds for the car to engage. Just to make it easier to understand, this is what happens when I leave my house to go to work.
Start up the car, starts fine, let it warm up, idles smooth at ~700 RPM. Put it in reverse, back out of my garage, put it into drive, wait four or five seconds for the car to actually go into drive, then apply the gas. [NOTE: Just recently I found that sometimes the car will not go into drive, it may just sit there and stutter at around 400-500 RPM. I can apply gas to get the car to move, then when I start to move forward a bit I'll hear a grinding noise coming from the front passenger side of the engine as the car goes into drive.] If I apply 15-20% throttle, car feels and shifts almost normally. If I apply 30-40% throttle, the revs climb quickly to about 3k, then bog down to about 2500 when I get close to 20km/h, then shifts when I hit 20km/h. Now when it shifts to second gear, still at 30-40% throttle, the revs immediately climb quickly up to 2800, stay there for a few seconds, then they start to climb normally to about 3500. Car then shifts at ~43 km/h. Now I'm cruising down the street at around 60km/h in 4th gear. To overtake a car, I apply about 70-80% throttle, and the car will rev to 4500, sometimes 5500 RPM, and stay there until the speed slowly climbs to about 80km/h, then it bogs down to 2500-3000RPM and stays there to maintain speed. Normally, if anyone were to do that in an auto, when you apply the 70-80% throttle, the car usually downshifts to speed up faster, then shifts back into 4th at around 75km/h. Now, cruising along at 75km/h, I catch an amber, and I have to brake a little hard to stop for the red. When I come to a complete stop, the revs will stick at around 1k RPM for less than a second, then the car jerks like I had just put it into drive, and the revs go back to normal.
That is basically what its like to drive the car right now. I have done some searching on the site and tried troubleshooting it myself, but nothing I did seemed to help at all. So far, I've cleaned out the TB and IACV filter with carb cleaner, and replaced the fuel filter. I'm thinking it may be something to do with the TCU, tranny fluid, spark plug wires, maybe even the fuel pump. Anything else at all that anyone would be able to suggest would be greatly appreciated.
