The Beast broke down - any ideas?
I know, I know, this is a turbo thread and mine is NA. I post here because there is a large amount of guys who post here who have chips and who might be be able to give me an idea what my problem is....
OK. Had chip installed couple of months ago. For last month have had fairly nasty flat spot at about 3500 under acceleration. Take foot off throttle, is fine. Was driving up Flagstaff Hill Road the other night (moving house, so had car load of stuff) - and those of you in SA might understand how unpleasant a road that is to break down on - and the usual flat spot hit. However, I am going up this rather steep hill and kept foot on throttle. Flat spot turns into something else.
The engine just about stopped. Became totally unresponsive to the throttle, revving at just above stall, shaking all over the place and I am slowing on hill drastically. Manange to roll to top and find spot to pull over. Car is jumping around, about to stall, no response from throttle. Turn off. Wait a min and restart. Was fine and drove home.
Took to dyno guys next morning, they run on dyno, cant find anything. Take them for a drive and eventually it does the flat spot thing as it always has. Not sure what it is yet, but replaced plugs. Should also add that it has been surging a bit at low revs (hence plug change idea). I had not been ignoring the problem by the way, I was going to just leave it until its next service (not at Ford) in a week or so to get it sorted.
I have my own ideas what's up - but just wondering if you guys have had similar experiences or have any ideas what is going on? I would suggest non mechanical but electrical, possibly fuel management.... but that is my uninformed opinion. Is there a chip issue? I am thinking disconnect chip for few days to see..... Oh, and I should also add that the guys who did the chip are busting to find out what's going on and have been great - thanks guys!
Also, my clutch is dead - see next new thread.....
