ToddF Posted June 10, 2019 Share Posted June 10, 2019 That picture with the yellow arrow is the tfi module, typically it is placed on the distributor but it looks like they placed in a different location already, which could be good or bad depending on heat soak. It also looks like the housing with the cooling fins was designed because of heat soak. I would try the wire wiggle test on the tfi too, doubtful that is the cause. But it should unbolt pretty easy, one tip: the tfi is like a 4 or 5 mm bolt and most sockets don't fit in the plastic opening very well, so I have had to tap the socket in or have a thin wall socket to be able to get the bolts loose. I know you replaced the MAP sensor, not sure if that is a BAP or MAP, the map will have a vacuum line going to the manifold the bap will just read the barometric pressure not manifold pressure, either way the boat would still run just crappy. I used to keep a TFI module in my car just in case. Now I keep a tps in my boat Link to comment Share on other sites More sharing options...
