RE: [SPOC] HARD STARTS WITH NEWLY BROKEN IN MOTOR

[Scott W. Thomas]

What about your coolant temp sensor? Is it possible that the faulty sensor is causing a problem with your warm starts?   Also, make sure that you don’t have a fuel injector that is leaking and causing fuel to puddle in one of your cylinders. This would cause very hard starts and would be overly rich and run rough until the fuel was burnt up….   You might want to consider posting your concern on SaturnSpot.com message forum under technical as well.   Scott W.

It starts totaly fine when cold, but after it warms up and you go to start it, it will stumble and start really hard and the tach will drop to like around 300 rpms then catch back up to around 900 and idle fine. I dont understand what it going on because it only happens when hot, and it idles fine. Some more info in the car is.. It is a 95 saturn turbo. JE forged pistons 8.3:1 compression, and gapless total seal rings, filed to 18 thousands for top ring and 15 thousands for middle ring. I am running a SDS and nology wires, Relocated coil tower on top of valvebody cover. I am using NGK plugs 2 steps colder Something like BCPR7ES-11 (I think thats the number) they are gapped to 30 thousands. It runs great when under boost at 10 psi but it really scares me when i am far away from civilization and it almost doesnt start. And right now the motor has 500 miles on n at 400 miles and everything is great except the starts, and maybe a little skip when accelerating not under boost. ANY HELP IS APPRECIATED Thanks Tom
