Good Morning, I recently posted about a snapping a MAP sensor bolt, but I wanted to post with background for people to help provide some advice. I just finished relaxing a head gasket using the gasket masters videos and @NutzAboutBolts videos, and everything seems like it went great! I just about had the car together and decided I wanted to clean the MAP sensor, but the bolt was seized and I snapped the head off trying to take it off. I thought “well, hopefully it still runs”. I finished putting everything together, added oil and coolant, and put the car into maintenance mode. It ran for about a minute before stalling, and it didn’t sound like it was misfiring. I had my scanner hooked up and it populates the following codes P0107 - MAP Sensor Circuit low P0351 - Ignition Coil A Primary Control Circuit Open P0352 - Ignition Coil B Primary Control Circuit Open P0353 - Ignition Coil C Primary Control Circuit Open P0354 - Ignition Coil D Primary Control Circuit Open P3190 - Poor Engine Power Obviously it’s terrifying going through a big repair and seeing MORE codes populate (although to was nice to not see the miss fire code) I read that an issue with the MAP can cause the rest of the codes to populate, and was wondering if the snapped bolt could be effecting the MAP sensors ability to read pressure? Any thoughts on the codes above, and how I can further fix and trouble shoot this car? Thanks for anything you can help with.
If you think the map is leaking you could just take a little goop with pointy applicator go around base of sensor set in hole with no screws applied allow goop to set then apply the 1 screw gently as to not offset sensor in hole creating flow by .
yeah, it’s the one 10mm bolt that goes into the intake manifold right next to the throttle body. Just remove the whole intake manifold and drill the bolt out or if there’s still some bolt sticking out, use a vice grip to unscrew it.
