94 2.3l 5sp, stalls
Orginal problem with missing, rough idle, replaced wires, coil pack ,plugs, ICU(solved most of the problems) was also getting other codes related to EGR, replaced EGR Vac. sensor, DPFE, cleaned and test EGR, installed new gasket for EGR. Now engine will run fine at idle for 20 -30 minutes or 5 -10 min. driving. It stalls and will not restart. Have to let it completely cool down and it will restart and run run good for another 20 min. I connected the old ICU and grounded it to see if it would restart but no luck. I also replaced the ECU and fuel pump relays, fuel filter, the fuel pump(what a pain.) Still have the same issue. I will try to spray starter fluid next time after it stalls, but I really don't think it is a lack of fuel issue because when it does stall you can smell gas. Hope that some one else has been down this road and know of a possible fix. I hate to spend the bucks on a ECU(computer) but I don't know what to try next. Thanks in advance for help.
