tuppscivic Posted November 21, 2008 Share Posted November 21, 2008 I swapped a phase II 2.5rs engine into a 99 Subaru legacy outback and am now having strange problems? I used a iacv out of a 97 impreza and swapped all of the sensors that didn't mate to the 99 phase I wiring. I ended up cutting and soldering the phase II injector clips onto the 99 harness so they would plug right in. The issue that I am now having is the car will idle a little higher than normal at warm up, but as soon as the car is warm and the idle drops down, two of the 4 injectors will stop "ticking" and drop out. It used to be cylinders 1 and 4, but after resoldering all of the connections, cylinder 1 and 3 drop out. I checked for loose connections, and am reading 13.2 volts at all of the injector clips when the car is running. I used a screwdriver to listen to each injector, and 1 and 3 do not tick at all at rough warm idle. If I unplug each injector one at a time, #1 has no change in idle. Unplug cylinder #2 the engine dies. Cylinder #3 has no change in idle. Cylinder #4 the idle slows down and than starts to idle better and cylinder #3 starts to fire to make up for #4? I have no ideas what might cause the two injectors to cut out at warm? I tested the injectors them selfs, and they resistance test fine. Could it be a sensor? Or should I resolder the clips again? Please help, Im pulling my hair out on this issue! Quote Link to comment Share on other sites More sharing options...
bobjr94 Posted November 21, 2008 Share Posted November 21, 2008 If the engine is idling to fast the ecu will cut fuel in order to try to keep the speed down. When you rev it up do the do the 2 injectors come back on ? Quote Link to comment Share on other sites More sharing options...
bheinen74 Posted November 21, 2008 Share Posted November 21, 2008 is your timing belt 100% on the correct spot- sounds similar to when a ej22 is one tooth off time, Quote Link to comment Share on other sites More sharing options...
tuppscivic Posted November 21, 2008 Author Share Posted November 21, 2008 The injectors do not seem to come back on when I rev up the motor. It rev's like its still running on two cylinders. I can shut the car off, start it back up, and as long as I put the motor directly in drive the car seems to run fine? Its when I put it back in park when the car drops down in idle that it starts the rough idle again. Quote Link to comment Share on other sites More sharing options...
tuppscivic Posted November 21, 2008 Author Share Posted November 21, 2008 Havent ajusted the timing belt on the swap at all. My buddy said it was a pain in the butt, and it has low miles. Quote Link to comment Share on other sites More sharing options...
tuppscivic Posted November 21, 2008 Author Share Posted November 21, 2008 What should I check for to correct the high idle? Vaccum leaks could cause this? I will check timing tonight and get back. The ecu also threw a code for higher than expected idle, and low injector circuits in 1,2,and 3. I think because of me checking the injector clips with a noid and not resetting the ecu afterword. The noid was dim on the non-working injectors, but brightened up when the engine was rev'd. Quote Link to comment Share on other sites More sharing options...
