2008 PT LX Model. For some time now, it didnt bother me before but now it is but, It idles a bit rough. I have a few ideas/possible solutions to this but I want to get opinions before I start doing these ideas.
Idea Number 1- Cleaning out the Throttle Body and IAC. Mechanic says to just replace them if they are the cause but what could the harm be for just cleaning them out? Not spraying cleaner directly in there and just spraying on a rag and cleaning it out.
Idea number 2- Possibility that the Top and lower Mounts are not alligned. I had both replaced, 1 after I bought it which was fixed complimentary by the seller/dealer and the Top replaced about 6 months later. Where I believe the issues started. I never knew that alignment of motor mounts was possible until recently and explains a lot of what is happening.
In short on the mounts is this. Loosen the Top and Lower Mounts, Jack up the engine to rotate it a bit and align it properly. How to do this is fairly simple. In the picture I uploaded, You measure in Millimeters between the 2 red dots in the picture. So, with both Mounts loosened, the engine would sit between 122-124mm. You jack up the engine until the distance between those 2 red dots is 119mm and you tighten both mounts down again. So, you use the hole by the mount where the fuel line clip that holds the fuel line in place as one point and the middle of the bolt with the red dot as the other point. Once it is at 119mm, 90% of vibration issues are fixed. According to the video. This has worked for most but not others. Others mentioned it was Throttle Body and IAC, some the Center Mount which mine is okay, and some had misfires which mine is not doing.
What are your guys thoughts? Anything else I should look into as well?
