hogweed Posted October 19, 2014 Share Posted October 19, 2014 i'm picking this up tomorrow and wanted some feedback on possible causes. PO states the car just shut off one day. no loud noises, overheating or anything it just turned off. he had it towed home and was able to start it when cold but it now runs very rough. he replaced the coil pack, and "a bunch of sensors" but it didn't clear it up so he bought another car. smoking a bit out the back but not terrible (oil smoke) and no pressure in the coolant bottle. any thoughts? thanks in advance G Link to comment Share on other sites More sharing options...
idosubaru Posted October 19, 2014 Share Posted October 19, 2014 i'm usually suspicious when someone has a non or poorly running car and has tried work/parts like that. timing belt - broken, jumped, tensioner or pulley failed and compromised timing MAF sensor Cam/Crank sensor Fuel pump Cylinder misfire (plugs, wires) Idle Air Controller 1 Link to comment Share on other sites More sharing options...
hogweed Posted October 19, 2014 Author Share Posted October 19, 2014 upon further review: smoke is unburned fuel...too rich unplugging #1 wire from coil has no impact. others change idle when unplugged at temp light seems to stay on for 15-20 seconds but goes out Link to comment Share on other sites More sharing options...
nipper Posted October 19, 2014 Share Posted October 19, 2014 AT Temp light working normally. Coil wire not changing things can be a burnt valve. How many miles are on this? Is it possible to get the old parts that he replaced and put them back on? When people just start replacing a lot of sensors they can make things worse or impossible to solve.

porcupine73 Posted October 20, 2014 Share Posted October 20, 2014 What's the idle rpm roughly? Not sure if this is relevant but just mentioning it since it comes to mind re: the unplugging #1 plug wire. I remember an old EndWrench article said something about if for some reason the ECU doesn't think it can reliably control the idle RPM, it will cut the #1 injector pulses.

nipper Posted October 20, 2014 Share Posted October 20, 2014 Running rough, lets start with the biggest PITA unfortunately, the plugs. DO a wet and dry compression test and lets go from there. At 234K miles even if it is a burnt valve, I wouldnt recommend on repairing the engine, but rebuilding it or replacing it. Link to comment Share on other sites More sharing options...

hogweed Posted October 20, 2014 Author Share Posted October 20, 2014 (edited) It is a sound way to go. any guidelines for what year motor to pursue? can a motor from a pre-1995 work? there is a guy selling a 91 w/ 2.2 but i don't know if it would be compatible Edited October 20, 2014 by hogweed Link to comment Share on other sites More sharing options...

lmdew Posted October 20, 2014 Share Posted October 20, 2014 90-98 will work. the 90-94 will require you to put a 95 intake manifold on and work around the EGR if your engine has one. Link to comment Share on other sites More sharing options...
Rooster2 Posted October 20, 2014 Share Posted October 20, 2014 Lots written on this forum about swapping in a 2.2 into a 96-99 Legacy. Just search around and read a lot. I swapped in a 95, 2.2 as a direct drop in. Car runs great. Link to comment Share on other sites More sharing options...
3Pin Posted October 21, 2014 Share Posted October 21, 2014 I have a 98 2.5 with 180K runs good with fresh head gaskets. It would be a simple swap. $500 for the motor. Link to comment Share on other sites More sharing options...

I swapped in a 95, 2.2 as a direct drop in. Car runs great. this was what i had been told. want to find a lower mileage 95 motor close to here (had a wrecked one w/ 105k on it but i fixed it instead of parting it). i will search, read and ask questions once i find one. i really think this motor is gone Link to comment Share on other sites More sharing options...
nipper Posted October 21, 2014 Share Posted October 21, 2014 Well lets not jump the gun just yet, do a little more diagnosing first. Link to comment Share on other sites More sharing options...
hogweed Posted October 21, 2014 Author Share Posted October 21, 2014 Well lets not jump the gun just yet, do a little more diagnosing first. you're right but i saw a lot of oil smoke coming from under the hood when it warmed up, has ZERO power.....it literally would not make it up on to the deck of my rollback.
