when metal gets hot it expands.. maybe it could be that problem with the leads. any kind of resistance on leads could affect the engine.

what i think they mean with a higher temp waterless coolant, that the boiling point of the fluid is higher. the coolant system works like a pressure coocker. take regualr water as coolant ( not a good idea but for the example) boiling point of regular water is 100 degree C. but when you alloq the water to be pressurerised it coud mean that the boiling point becomes 110 degree C. when water start to boil (gass is greater volume than liquid) the pressure risses and then the radiator cap would depressure the system by venting it to reservoir. so if you could increase boiling point of the coolant it could take higher temps. but why......? like studoc 72 said you need to desperse the heat from the engine to keep it around 80-90 degree C. i would stick to manufacturer recommended coolant. special with the added dopes to prevent corosion due mix of metals used in the engine and coolant system. correct me if i'm wrong ;)

better get a new clutch kit ;)

on boost u need "extra fuel" and some more retardation (dunno if it is good english) of ignition. if this is not provided it could missfire. special when you say that this problem came after plug replacement, check brand/gap of old plug and new. replace the old ones and see if problem is solved. something that could happen to al techs is not putting the cap good on plug. thus no sparksz goodluck

if that is not the problem you could try and upload a video while at idle and while driving so let some tech guys from here take a look and listnen. good luck!

yeah that's the way to reset. and to test the map sensor its real easy. turn on ignition and measure voltage of sensor at stationairy. should be around 1.4 volts (thats normal for most vehicles) and let some one Wot it should go to 4.5/4.8 volts.

check map sensor and lambda sensor. these will calculate the amount of air/fuel being used for the engine. if these check out correctly you could check for any vacuum leaks in the manifold. an extra dosis of air in the manifold could lean out the mixture. or your fuel delivery system is to low. (broken injector, blocked fuel filter/line), broken FPR. cheers, wouter

is your fuel pump relay still good? because if you bridge it it works...

if your battery is fine you can try to check if your starter motor still works by shortly connecting a 12v+ to the starter. if it turns you know that the starter is fine. if the starter is fine you have to check your starter relay. because you can't start working diagnostics on the fuel system if the car isn't cranking. good luck trouble shooting.
