Rampage Posted March 2, 2020 Share Posted March 2, 2020 Our 95 and 97 EJ2.2 will do exactly the same thing when the MAF sensor is bad. Happened a couple of times. Get one from a yard. The last ones I pulled myself cost me $25.00 a peace. 1 Quote Link to comment Share on other sites More sharing options...
alykat Posted March 8, 2020 Author Share Posted March 8, 2020 Turned out to be a faulty dealer installed keyless entry / anti theft system. Once I disconnected it and reconnected the cut and patched in wires in the original wiring, it starts and runs great. 1 Quote Link to comment Share on other sites More sharing options...

lmdew Posted March 9, 2020 Share Posted March 9, 2020 The Subaru ones are usually pretty good. It's the aftermarket ones I always pull out. Quote Link to comment Share on other sites More sharing options...
dameson Posted March 9, 2020 Share Posted March 9, 2020 Had a similar problem with my previous Forester. The IAC was the culprit. Quote Link to comment Share on other sites More sharing options...
