Thanks MM

they claim the problem this time was bad "ignition coils"

I am going to drive it for a few days and will report back.


Thanks for all your help

Do you have the original coils or the updated ones? I know the originals aren't very reliable.

 

Not sure if I have the original coils or not.


Would the coils be changed when the motor is swapped out?

I am on my 2nd engine.

It was changed in July of 2005

no they would not have been changed..

The compression numbers, maybe carbon build up? But I know thats not the case.

Edit: Sorry Swoope I mean't carbon build up My mistake

 

could you explain this carbon lock up???

beers

 

what is the best way to clean out possible carbon build up?

A product called SeaFoam worked great for me on piston motors. there is also a water injection process that a lot of the old rotary guys swear by.

 

that is absolutely 100% correct.

 

how the F is diagnosis not covered? tell him to call the fing hotline and get it authorised- you are in vegas and already on your 2nd motor tell him to speak to Mike Allen directly.

 

u can also get diff numbers if the engines hot or not, i think the spec of 6.9 is when the engines hot....i did a test on an rx8 once when it was cold and got like 6.1 and was like wtf!!!!!!! haha


mac 11 i love ur sig, days of thunder ftw!

 

Compression testing is affected by a lot of things (the RPMs just prior to shut-down will affect latent oil injection which can artificially raise the compression a tad, for instance), but the hot numbers are lower than the cold number, usually.
However, three-days-cold or so will see some weird effects as well.
If you want to just make yourself happy, let the motor cool down about 3 or 4 hours and then run the test. You will get your highest numbers.
For accuracy though, you should run the test with the motor "glove-hot".

 

wow... good luck to you
