Hi again! Still trying to work the bugs out of my '89 Sentra 1.6 ltr. with 5 speed manual, A/C and Throttle body fuel injection. 88,850 miles!
Engine cuts out (no spark I think) when the accelerator is pressed hard under load, say going up a hill or trying to pass. I hear & smell the gas going in but the engine cuts out beyond half pedal travel and returns to normal (with some sputtering) when I ease up. Does this everytime.
I had been concentrating on the fuel & vacuum system, not to mention timing and plugs, but I got curious about the crank angle sensor and distibutor itself. When I removed the cap, the was a small amount of oil IN THE DISTRIBUTOR cap! Lucklily I had a used distributor unit, unbolted the old one and put the replacement one on and cleaned up the cap. (No error codes on the computer by the way!)
The car ran like a champ ... for a while then started doing exactly the same thing as above ... cutting out under load. Would it be reasonable to assume the second (uesd) distributor is bad too, allowing oil in to the crank angle sensor? Was this a common problem with the 88 - 90 Sentras? Could there be a root problem causing the distibutors to go bad?
I should add that I have to other "issues" at present with the car: A) The fuel pressure is too high, around 45 PSI according to the home-made guage I have installed at input side of the fairly new (34 months and
3000 miles) fuel pressure regulator. AND B) the timimg may be off due to broken timing chain tensioner and / or timing chain jumped one tooth. These things may or may not be related to the above problem(s).Anyone who's had similiar trouble and found solutions - thank you for your help on this one!
