Checked the spark plugs, doesn't look lean. Did compression tests on all cylinders and it ranges from 120-130. Does that sound right?

 

usually 150 to 170 with not too much variation from cylinder to cylinder

 

Did all the plugs look the same?

 

your compression should be 175 across the board you may not have run it long enough if there all 120.

The ticking noise is a lifter that has failed. Mine does it at idle. Replace the lifters.

The overheating is the issue i would be worrying about. That's a head gasket if it really is getting hot under boost.

 

On a evo 9 the comp should read 130 .. remember his mivec gents ....

Comp is good ,, did you check your spark , change plugs , check injector clips ect

or you could of called ...

Dead coil ???

check injector clips.. make sure they are all on tight... if all the plugs look good check the coil packs.. figure out which cylinder is misfiring...a good way to find out is idle the car.. unplug each spark plug from the wire or coil one at a time.. if you get to one and the car sounds the same with that coil unplugged thats most liekly the cylinder with the misfire.. if you have good spark to that cylinder.. you must not be getting fuel since you said compression was pretty consistant from cylinder to cylinder. id start with simple things than go from there

 

Hey Mark,

Thanks for your input. I've been busy as hell with my work, I havent had the chance to look at the car too much, last thing I was able to check was the compression and the plugs. I'll give you a call tomorrow and we can go through some steps if you can help me out.

Thanks Andrew for your input also, I'll check it out and let you guys know.

...any idea why the car was overheating as soon as I hit any boost?

 

do a leak down test... that will tell you about the head gasket.. i think if your oil is like milky color.. coolant is leaking in.. which could explain why you are over heating.

 

I checked the car out today. Its an AEM problem. The AEM is not firing the #2 injector.
The box will be going back to AEM and then she will be good as new.

Thanks for taking a look at it for me. Check your PM plz

 

Hey,

Nothing wrong with sounding like a Subaru!!

 

there is when your car is rocking a diamond star badge

 

LMAO!!!

thank god it wasnt a hgasket or a rod knock or lifter, its a scary thought when you just got tuned by TurboTrx earlier that week and you had a problem...

Honestly this may just be me and my redicuous mindset but sean ivey isnt too far from TTz and is IMO a better tuner... Please dont all start a war this is just my oppinion. nothing agenst TTz

 

Same thing happends to me. Checked the spark plugs and the #3 plug keeps fouling.

 

Anytime.

Keith
