Guest kinkydeviltom Posted January 4, 2012 Share Posted January 4, 2012 hi, any help would be greatly appreciated, 1993 supra na Had a pipe burst on me the other day, the pipe at the rear top of the engine which links into a H shaped metal pipe system, i fixed this pipe with a new pipe and haven't really driven the car much over xmas until i went back to work yesterday, Then yesterday about half way to work (bout 10 mins) the engine suddenly started misfiring and got worse to the point where all the power had gone and it was struggling to move away, then it went and came back, went and came back and after about 5 minutes it went completely normal so i assumed it might have been water in the plug holes and it had cleared out, but then on the way home it did it again bout half way home and then the same today both on way to and from work, i had my plugs all changed about 2 months ago, 2 new leads and others tested fine, all compression test fine i checked my water levels and all seem fine so not loosing water i don't think, it only seems to happen for a few minutes not as soon as the car has warmed up as that only takes a couple of minutes but around 10 mins after driving it any ideas on what might be up with the supra or where to start?

barneybrendan Posted January 4, 2012 Share Posted January 4, 2012 have you actually checked to make sure water isnt covering your plugs sat between the 2 cam covers. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 5, 2012 Share Posted January 5, 2012 Sounds like a classic case of water in the valley as Brendan says. Remove all plugs, turn engine over on starter for 10 or so seconds, mop out ant remaining water, dry plug ceramics and plug lead ends, refit everything, take for a longish (30 minute) drive to fully dry out.

Guest kinkydeviltom Posted January 5, 2012 Share Posted January 5, 2012 Hi chris, yeah im starting to agree as i had the rear piPe burst and just thought it would evapourate out but remembering what it was like last time water was in at urs, this time it was only intermitant but just been to footy and it was identical so will strip down on weekend, ow btw i fitted new rad, went back to original air box and in the end got another throttle body and swaped them over and my supra was purring lovely, well until this happened n e ways, Thanks again for the work you did and advice you gave, Tom Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 5, 2012 Share Posted January 5, 2012 No worries Tom, I am sure another proper dry out will sort it, you know what to do now N/A TB's are a PITA, I am collating scope data on these, some have stuck idle control solenoids, some have dodgy TPS tracks, some are mechanically worn out with leaky butterflies. New ones are silly money Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted January 7, 2012 Share Posted January 7, 2012 I have new stainless pistons in stock, and new seal kits, everything you need if they need parts. Quote Link to comment Share on other sites More sharing options...
Guest kinkydeviltom Posted January 7, 2012 Share Posted January 7, 2012 How much would it be for 2 pistons and new seals delivered, ive ordered 2 rear calipers but if its cheap enough to fix mine. Ill fix and sell mine? And how much would 2 rear disc set me back, mine have hardly any wear but due to uneven wear im considering replacing? With new pads on they should just evenly wear back shouldnt they? Quote Link to comment Share on other sites More sharing options...
