Gixxer Squid Posted July 29, 2011 Share Posted July 29, 2011 Running a tech 3r on brandnew engine with 650cc RC injectors and 4 and 5 keep fouling out after 100 miles or so causing car to run like crap. Pull all plugs after a short dirve and 1-3 and 6 are tan at tip and dry but 4 and 5 are black and slightly wet. Use cloth to dry off and put back in and run car for a minute and pull back out and they are wet again. Clueless unfortunately at the time on whether EMS can control the amount of fuel each injector deposits? Possible solutions as injectors are brandnew. I suppose if EMS can control that then a simple tune will solve this if each injector can be isolated. Running fuel pressure at 42 lbs. Thanks for input.

dexter72 Posted July 29, 2011 Share Posted July 29, 2011 Try swapping the injectors around and check plugs again. Don't know what engine you have. Quote Link to comment Share on other sites More sharing options...
Gixxer Squid Posted July 29, 2011 Author Share Posted July 29, 2011 (edited) Guess i could do that but got to take the fuel rail off to get to them which is a pain. Stroker motor. car is turbo charged, hence the post here. Edited July 29, 2011 by Gixxer Squid Quote Link to comment Share on other sites More sharing options...
