Lacoste82 Posted March 27, 2012 Share Posted March 27, 2012 Hi guys, just recently i got the Supra(J-spec N/a) out of her winter sheltor and back on the road! The battery had died somewhere along the winter, and i put in a new one! I took her out for a spin, gently, letting her warm up, no high rpm`s or such, just a long nice cruise. But at the second day, i entered the highway and pushed her to get up to speed and suddenly the engine light flashed for about 5 secs or so, i slowed down and pulled to the side of the road, and strolled along at around 30 mph and the engine light turned of - i did the trick with the diagnosticks port and got an error 42, which apparently has to do with speed sensor circuit(had this one when i had a speed delimiter installed, but i removed the delimiter 2 years ago. and away went the error code, and it hasnt showed again before now) On top of this, ive now noticed that i only get around 11 miles pr. gallon, and that is something like 35% less than i usually get! The "problem" is(atleast when it comes to figuring out whats wrong), that the car runs very well, no problem in acceleration, keeping a steady idle or anything like that! So what could be wrong!? Could it be the ECU acting up, taking into consideration the flashing engine light and quickly passing error!? Maybe a lamba sensor!? I have a steel manifold on and decat(full Blitz nåur spec), no cats at all. Cleaned airfilter, put in new oil and oilfilter! All and any ideas to what could be the issue, are most welcome! Thx in advance! Quote Link to comment Share on other sites More sharing options...
Digsy Posted March 28, 2012 Share Posted March 28, 2012 You could check the brakes haven't siezed and are binding on. I seized three out of my four calipers over winter last year (not all at the same time) and it knocked a fair bit off my mpg until I changed them out.

I got around 130miles from a tank last year due to a seized caliper, add on the cost of a pair of discs and it was an expensive trip.
