Rough idle, smoke, low mpgs
My 95 PSD just rolled over 193,000. Every time I start it, it lopes pretty bad until I step on the go peddle; after that it smooths right out.
The fuel economy isn't the best, on a recent trip I got 14.5 on one tank, and 17.3 mpg on the other. Both were at highway speeds, one with more passing. At one point I got 20/21 mpg.
The last symptom is a good deal of white smoke on cold starts, followed by a time period of some translucent blue smoke.
I recently replaced the GPR and changed the oil. What next? Plugs? Injectors?
Thanks in advance for the help guys!
