We'll I just put a new head in my evo iv replaced with Tommi makinen head cams etc,new belts new gaskets head tourqued correctly now every time in push it in high rpms it just turns of then I have to start engine again.

Also another problem I am experiencing is when I drive the car for about ten minutes when it's hot it's very hesitant,jerkin,no power to the point where I can't even drive 20km per hour and it just dies when I try to accelerate.

Please help me I'm about to junk this car as it's been pissing me off so bad problem only occurs when I drive it for ten minutes or so and then it will just jerk ,no power,stall, can't even move it until I leave it for twenty mins or so .temp is normal on it no overheating or anything

Please somebody she'd some light on this for me before I burn this evo so much money spent and I'm not in a financial position anymore to keep throwing money at this piece of sh#%*. It has so many mods and I just don't know what to do ...........

Thanks in advance

For some reason I don't think these problems are linked I think they are two separate problems am I right? And also I have just installed my external waste gate and have have the vacuum hose from turbo to the inlet for electronic boost controller and a hose from the outlet nipple to the side external wastegate port and vented the top of the external wastegate is this correct .? Please evo gods help needed so badly have a young family and this is our only source of transport .
Thanks guys sorry for rambling on.

Maybe the timing chain is a tooth off

Thanks for your response but how could it be only stuffing up when hot??we timed it perfectly when installing new belt tdc.it idles fine but as soon as it's driven abit these problems occur it's got me stumped....

Wayne.kerr

Have you had this problem as we'll?

Bhsj13

are you currently tuned for your set up?

Wayne.kerr

Any input would be greatly appreciated thanks in advance

Wayne.kerr

No I haven't had a tune yet I want to take it but I don't think the car will make it to the local performance tuning garage

The top port of the wastegate should have a vac line going to your boost solenoid for your electronic boost controller.

Wayne.kerr

Ok is that to the in or out nipple of the solenoid thanks for your response

Wayne.kerr

Is that the in or out part of the solenoid bro?

NigHtcRawl3R

Port 2 should be it which I think is out.

Wayne.kerr

Cool thanks .any idea about the other problems I'm experiencing ?

NigHtcRawl3R

Start with that as your external could be causing your issues? It's a long shot but eliminate one problem at a time.

I highly recommend parking the car because your air to fuel ratio is probably screwed. Also, if the TME cams are more radical in the car than the stock ones then the ECU probably doesn't know what to do as you haven't taught it anything yet. Get it tuned ASAP.

Wayne.kerr

Thanks will try and do ASAP do you think that could get rid of all of these problems ,,well at least at the performance tuning garage the car will be in the best hands and with the experts that know a lot about these turbo cars
