95 E36 open/closed loop
My 95 325i has been a great car until I let it set for a couple of weeks. When I tried to start it, ( which ts has always jumped to life almost instantly). It turned over slowly at first the spun faster but wouldn't start. After a couple of more tries it started but has sputtered and is down on power. Pulled plugs looked ok,(Bosch Platinum) replaced with copper NGK's checked coils, all checked good replaced plug boots (old ones oily), replaced all valvecover gaskets. Replaced fuel filter. Now starts up instantly.
When it warms up (closed loop) it runs like crap, sputtering. Let it cool down, starts and runs great until it warms up. Want to check temp sensor and O2 sensor. Any suggestions????????
