rowanhol 0 Report post Posted June 19, 2008 hey guys my 535 started running really rough while driving through town the other nite especially under acelleration, sounded like it wasnt running on all cylinders. it got progresively worse and within a couple of minutes was undriveable so pulled over and it died. i could restart it but it would only rev up to 1500 rpm with my foot flat and would die if it tried to idle. at the time i wasn't thinking right so didn't think to check the exhaust for steam ie blown headgasket. i'll start it up and check it out when ive got some time this weekend but what else could/should i look for? thanks Quote Share this post Link to post Share on other sites

It is the blue one in the thermostat housing. Should have around 2.9K ohm resistance when cold, and this figure drops as the engine warms up. Quote Share this post Link to post Share on other sites
