Just bought a 04 M1 that's been sitting for 5 years. New tires and power steering pump ordered. Has high idle (1100+) and possible roller lifter noise on startup. Quiets down after a minute or so when cold. New oil change, Lucas added, then a bit of Marvel to the oil and fuel along with 93 oct. It has a K&N System and possibly a tune, but no way of knowing for certain until I can get it running without the current problems. It doesn't seem stock to me. I do have a ZR13 OBDII Diag Scan Tool. Can this tell if it has a tune on it? And is Electronics Spray Cleaner sufficient to clean MAP & other possible culprits to the high idle? With the shaker hood, are there any common problems with air fuel combo? Also spring problems on TB? Any positive inputs is appreciated. I am relatively new to late model HP. I have built 2 60's era cruisers, but nothing new. Thx.
