chilkoot Posted November 13, 2011 Share Posted November 13, 2011 When cold, car will start and idle fine @ ~1100rpm. After a minute or two it stalls. After it stalls it will crank, and fire, but stall instantly once it catches. After doing this a few times it will crank, but wont fire until it's cold again. It's not: Fuel filter (replaced) Fuel pump or ECU (no change with b+ and fp jumped) MAF (no change with MAF unplugged) with heavy throttle while warm it will fire and rev like hell, but sounds ugly and rpms will cut out to near stall and jump back up intermittently, sometimes stalling. I'm thinking the driver side coil dies when it gets hot, anything else it could be? Plugs, wires, caps, rotors all replaced 3 years/20k miles ago during tb/wp job, coils are original @ ~150k miles. Thanks all. Quote Link to comment Share on other sites More sharing options...
chilkoot Posted November 13, 2011 Author Share Posted November 13, 2011 Sorry, it's a 93 and I can hear fuel in the rails with the fuel ecu bypassed. Quote Link to comment Share on other sites More sharing options...
curiousB Posted November 14, 2011 Share Posted November 14, 2011 Coils are problems for these cars so you may be onto the problem. You should see serious drop in power by a bum coil. Also should see red hot CAT on the bad coil side after a bit of driving. Quote Link to comment Share on other sites More sharing options...
steve2006 Posted November 15, 2011 Share Posted November 15, 2011 Also check the crank position sensor and wiring, these tend to go intermittent when warm. If you have some freezer spray give it a good spray when the fault appears then see if the engine starts straight away. Quote Link to comment Share on other sites More sharing options...
