I have a turboed 2.8 4-speed that I've replaced practically all sensors, fuel pump, filter and injectors, etc. It runs much better than when I got it, mainly due to the injectors, but now it almost dies when coasting not under load. It will come back to life when I hit the gas with a bit of a jerk. No PCV valve, no vacuum leaks, MAP sensor tested okay. I did some research and saw TPS as a possible cause, idle adjustment screw, and someone solved a similar issue because there was too much teflon tape on his temperature switch (needs to be grounded). Any other opinions or ideas of what to look for?
