Hi guys, Whilst I am newly registered I have abused your knowledge for quite some time having owned an Rx-8 for the past 5 years. I am on my second car after selling my previous one before some travelling.
As you know I cannot post this new thread anywhere else. Too miserable to get involved with off topic chat:) and not really confident to offer any advice of my own its only my thank you posts that will get my post count up...
Recently My car went in for a service. I should add that I have a 2008 with 25k on the clock. I had felt that it needs a service months prior. I always get it serviced main dealer primarily to maintain its full service history. Actually its the only reason.
Prior to it going in I had asked them to investigate a grumbly idle symptoms. My own research had flagged up the potential for compression issues being one of many possibilities. So I also had a compression test done. It passed with honors so that was a relief. During the service I had the usual Air filter, oil filter and spark plugs renewed.
This had improved the idling grumble significantly but I was advised to change the leads.
Literally days later a cell came on. The catalytic converter was failing. ( Note to anyone who does not know. Sell your used Cat to a Metal Dealer(£110+))
since then I have replaced the CAT , Lead and coils
Cleaned the MAF and throttle body.
20 break stomp
The car is running like a dream. Great power, smooth idle.
So here's my issue.
From a cold start I find the engine starts immediately, idles up at about 2000 rpm before dropping itself down to the 900 mark. It does this without missing a beat. However if I touch the throttle in the first minute or so It revs terribly and feels unbalanced.
Where should I look in your opinion?
I'm no mechanic everything listed above is my current experience in tinkering
