The saga continues.
My rx8( 6sp, 04 gt with 72k)was taken in 6 weeks ago and diagnosed to need a new engine because of repeated flooding problems(13x in 3 years). When I picked it up with a new engine about 4 weeks ago it ran horribly. While acerlating the engine would bog down so bad it would actually slump you forward, and then it would resume accelration. This happened in all gears but most noticeably in 1-3. I immediatly took it back and they confirmed the problem.
Since then they have done the following.
1) Tested compression on new engine-passed
2) Replaced eccentric shaft position sensor
3) Replaced Cat and muffler also tested with out either
4) Replaced throttle bottle
5) Replaced fuel injectors
6) Replaced intake manifold
7) They have taken out a new rx8 and mine to compare with PID montior running and mine produces no error codes at all, even though it performs like crap.
Mazda continues to pay for my rental and honor all repair under warranty but I am getting tired of driving a crappy 6 when it's nice out and I want to be in my 8 with the roof open. I'm going through 8 withdraw.
Any suggestions?

 

Yeah, sell your current one and buy a new 8. In my experience, cars never perform the same way once the engine has been replaced.

 

I would consider selling it however I owe more than it's worth so I would take a bath on that one! The strange thing is that this performance issue didn't begin until after this new(reman) engine was put in. Since then they have completely retorn that engine back down to make sure they didn't miss something and then put it back together. Still no luck and no codes being reported.
There approach now is to begin swapping all other parts with known good until it runs right. I don't know how long that is going to take.

 

how long you had the car? ill try lemon law if its not too late. even if you got it used you should be able to do that.

 

I bought the car new in october of 03.
Even though It's had the repeated flooding issue from day 35 since and they have not been able to resolve it would be well beyond lemon law statutes I believe, however I do have an appt with my attorney this afternoon to discuss my options. My concern with litigation is that it could cost alot and I don't know what I could get. I'm sure Mazda has many a high paid attorney on retainer that are prepared to fight a case like this.

 

Sounds like the problem isnt the engine.....did they run tests on the electronics?
My wife's MINI had the same problem, it ended up being the computer. After a reflash it was all better.

 

That's incredible. You've almost got a new car. I would hope they don't fix it so you can get a new one at this rate.

 

The computer tests ok and they did a swap with a know good one. The PCM was replace about 8 months ago in an attempt to fix the flooding issue.

 

Did you say that you "flooded" your RX-8 13 times in 3 years?!?! I think thats a new record?

 

NO! I did not flood it as that implies user error! I am quite careful about short run times/warmup period and my rx8 is always in my heated garage.
Yes this car was towed in 13x since purchased for the same flooding issue.
Attempts to fix that flooding issue prior to engine replacment as follows
1) 3 new batteries
2) 2 new starters
3) Multiple sets of new plugs
4) Mulitple flashes
5) New PCM
6) New intake manifold

 

If the dealer can't fix it, they should be able to help you by getting you into a new or comparably new 8

 

I would have started demanding a new car way sooner. You certainly have some patience (13 time?!?!?!?).

lucky 13 baby

 

My patience was only because each time they claimed they had a "fix" and they gave me assurance they would stand behind the warranty for this issue even after my car eclipsed 50k since it was the same problem still occuring. It's clear to me now in hindsight that I should have been less patient but quite honestly the service manager I have been working with has been very nice and I don't question their effort as they have thrown everything but the kitchen sink at my car. The master tech mechanic working on my rotary has been working on them since the rx4., and has owned several himself. I don't think its his fault either. Bottom line though is I want a car that starts and performs since I paid over 30k, and have been waiting for Mazda to solve this problem.

 

I thought the magic number was 6 and then it automatically falls under the lemon law. You should have looked into that a long time ago. How long did you finance your car for? (if you don't mind me asking), I mean, you said you purchased it Oct 03 and you still owe more then it's worth. I purchased mine in Aug 03 and it's been paid off since last summer.

 

a heated garage means nothing...

 

^^^A heated garage will mean the motor is never cold. It will always be at least room temperature (70+ degrees). Very hard to flood an engine that is almost warmed up to begin with

 

Congrats "No Tears"! I'm glad you paid for your 8 in 3 years! I still owe 3 years before mine is paid for. Not sure why that matters to you???? but since you asked I figured I would amuse you.

 

a warmed up engine is about 170 degrees... i seriously doubt his garage is that warm

 

Is there a reason you answered like an ***? It was a simple question. Have fun with your lemon, ***!

 

Whoa, Mr tears, I didn't mean to make you cry. Just didn't see why it was your any of your business how much i owe on my car yet I chose to tell you anyway.
Don't be so sensitive!

 

Thats why I said "if you don't mind" in my post. It obviously offended you that I was pointing out what a dumb *** you are for buying a car you obviously couldn't afford to begin with. It's not making me "cry"; as a matter of fact, I'm gonna smile every time I read about your lemon falling apart.

 

It's so sad to see someone so angry at the world. You must have been teased alot as a child. I feel sorry for you mr tears. I hope you can get some help.

 

Tension

Not paying off your car in 3 yrs means you can't afford it?
