cosworth spluttering at my wits end with cossie at moment .when i drive car from cold it drives 100%.if i get caught in traffic or let car tick over till fans cut in car starts to splutter and will eventually not pull at all.the problem is temp related but car is only reading quarter way on temp guage its not boiling.i suspected sensors so i changed water temp sensor .air temp sensor and crank positon sensor but no change.any help apreciated

cosworth brakes.i recently done a 3 door cosworth under body resto.when i reassembled everything i turn on igniton . brake pump runs accumulator fills abs lights go out .when istart driving say past 10 miles per hour abs lights come back on .i suspected abs sensor so i checked all with ohmeter and they all read same 1200 ohms i think.can i check these when i spin wheel or what do i need .is an oscilliscope suitable.all teeth are clean on abs wheel ,i put vaseline around sensors is that ok.where you bolt sensors to calipers is pretty coroded and broke i wonder if sensor is slightly twisted and no longer square with teeth will this effect operation .any ideas appreciated
