ST with Check engine light & codes P0107 and C1290 - fixes?

[scubadown]

Battery looks good. 12.8VDC before starting 13.8VDC while running.

I've found if I start it with firm throttle and keep it running about 3,500 rpms until it warms up some it does run and seems to run OK. After starting it does flash the check engine light.

Snowbelt - can you tell me which side on the engine the MAP sensor is on (R or L), thanks.

Thanks Mike. Yep. Left side. Look for that sensor in the picture. Your hoses won’t be orange, they’ll be black. While it is running, check the codes again and see if anything different, or if it is still indicating MAPS issue. Replace those little vacuum lines.
