Turn-down exhaust after pre-muffler
Here's The problem.
Headeing back to work from lunch break ,temp is about 95 outside, Get in ,crank car it spits and sputturs. See black smoke(running rich-not normal) and it dies. Crank again, and it barely riuns. Rev to 4000 thinking maybe just needs a good clearing. Finally clears up. Dirving to work only 1 mile away from lunch spot, car dies 500 feet from office, coast in and park. Try to restart, nada. Lift hood look for anything obvious, all looks good. Restart with hood up...seems to run fine. ;Leave work at 6pm car runs fine and I drive 40 minutes to home not 1 hiccup. Go to Denver for work(I live IN SC) come back week later. Try to start car, Nada. Finally get it running and head to work. 5 miles in my trip car dies. Trailer home.
Start working on problem:
Test fuel pressure reads 30 to 35 psi. That's a low number so I put in New Pump.
Result= no good
Change Fuel filter (second time in 2 months)
Result= no good
Here's the kicker.
The car runs better with the hood up than it does with it closed.
I cranked it tonight, It purred like a kitten for 15 to 20 minutes, Then just suddenly dies. We she starts to die ,she puffs black smoke.
Something even stranger. Usually check enging light is on. Not tonight. It never came on and the light is good it lights at pre-start.
My thoughts:
bad coil? can't be this motor can run off 4 cyclinders if 1 went bad.
Bad computer? Possible,the computer did kill the check enging light for no reason
Bad crank sensor? Possible,but the computer should throw a light if its shorting or bad
Any help would be desired. Im taking to shop monday to pull codes thru a snap-on obdII Reader.
Thx guys
