Hello,

1). Recently I've noticed some issues with my 8. I've searched around the website but could not find issues that sounded like mine. Firstly, just this past week I noticed my acceleration bogs down in 1st and 2nd gear and clears up once it reaches 3rd gear and 4th gear (A/T). For instance, I'm sitting at a light or stop sign and take off, giving it a lot of gas and it goes nowhere until it hits 3rd gear. Sometimes when this happens the car starts rumbling or shakes until it clears up. Also, sometimes when it gets to 2nd gear, the car kind of rocks back a bit until it reaches 3rd gear. Any ideas what might be causing this?

2). I've also been having problems with my power windows going down. For instance, in the morning on the way to work my windows will go down fine. When I leave work in the afternoon when it's warm, my windows will not go down half of the time. Are the door panels getting too hot because of the summer heat that the motor doesn't function when warm? I'm at a complete loss with this one.

3). I've also had heating issues in the winter and cooling issues when it's warm in the past few months with the season change from cold to hot. Like my heating and cooling doesn't blow out of the vents as hard as it used to. It takes longer for them to either heat the car or cool the car. I literally have to turn it to max to get a huge airflow to come out of the vents.

4). Lastly, I'm in the market for a good radiator. After doing some searching, I think I'm going to go with the BHR radiator. The BHR website doesn't say if it's compatible for A/T. Any ideas?

Thanks everyone for any help, tips, or suggestions!

 

Whats the year model and how many miles on the odometer?

 

Also are you keeping it in drive or in manual mode?

 

It's a 2005 RX8 Shinka with 75k miles on it. I usually just drive it in automatic.

 

Does the acceleration problem still happen when you shift it over to manual mode and try accelerateing through the gears?

 

Well, I never drive it in manual mode so I wouldn't know. I would check but it's out of commission right now; waiting to change the radiator out.

 

**UPDATE**

It was driven in manual today and you could feel the problem just a little bit. I'm noticing more that I don't have any power/acceleration more than anything in 1st gear coming from a complete stop. 2nd through 4th is fine. It's noticeably misfiring now. I got a compression test done and was told this:

"Cylinder 1 is slightly lower than cylinder 2, we recommend a decarb".

This temporarily fixed the "hot starting" problems I've been having. I got no numbers or anything to show the results which leads me to believe my dealer is absolute garbage. Anyone have any thoughts? Thanks in advance for any feedback!

 

If you didn't get the numbers, then you didn't get what you paid for. Go back and have them either find the numbers or redo the test, not really your problem how they do it
