Help! White is sick.
About 6 months ago she started hesitating at acceleration...that progressed to a full "miss under load" - meaning, I'd have to feather or rapidly pat the pedal to get her to catch on and go. Then, she got to having spells - RANDOM - one time perfect , the next crank and crank with sputtering and BLACK sooty smoke, but then the next time, perfect. I took her in for repair, he changed a VERY dirty fuel filter, tune-up and set timing. All was good for two weeks, then it started again. AND TERRIBLE MILEAGE. The hesitation has been getting progressively worse, and now sometimes it won't start, or will stall while I'm driving if I dont constantly keep up the RPMs.
Sometimes it runs fine, other times it doesn't want to move. Its day or night, cold or warm, no in between with this thing. But it seems to do well in cold on initial startup...but if I stop at a store, come back in 10 mins - it is a 50-50 chance of what it is going to do. And today, stoppped at a light, took off - she died. And I like to never have got her started...then sputter, running rough, smell gas til I could get her up to speed (and high rpms). And TERRIBLE MILEAGE - REALLY BAD - try 3/4 tank from Lenoir to Gastonia and back.
I do not get any check engine light - the bulb does work (as I can see the light when cranking) - but it has not come on a single time when running bad (or ever).

I changed the Fuel Pressure regulator...and I have disconnected the Cold Start Injector - both gave no change. I don't want to keep throwing money at it - but I do want an "educated guess" if nothing else before she goes back to the mechanic. And he is a good mechanic - the clogged filter would have been a logical candidate before - but I wanted to see if any of you had run into anything like this.

Biggest concern is that I can crank and go to store fine. Leave store #1 with hard start and rough running...go to store #2, then she'll crank fine and run like nothing is up. In fact, I just ran out the road...started fine ran fine. Stopped two miles away. Restarted to troubles. Came home. Restarted to trouble again. Turned off. Sat ONE minute. Restart a little flooded, but it immediately cleared up and ran perfectly.

Just trying to see how reliable she is going to be over this snow that is coming tomorrow.

Any ideas?

Hmmm doesn't make much sense Grant. Ill just throw these ideas out there..

O2 Sensor bad? - but usually that will trigger a CEL
Dirty injectors? - Possible because your fuel filter was so dirty
Bad ground on the fuel pump? Could be causing the miss if the pump isnt running consistently and consistently feeding the lines with fuel
Clogged pickup on the fuel pump? Same situation as the ground

I agree with strech an o2 sensor can cause funny things definitly can disstroy milage. An easy check if you havent looked yet is battery and alternator. With cold temp. old batteries get weak and if alternater is starting to go bad it can cause similar problems. Just watch the voltage meter when you are having problems compared to when it is running right.

That is definitely the major issue without a doubt.

Voltage is good...no variation there. And it is definitely a "too much fuel" problem rather than a "fuel starvation" issue. I am going to use Blue as a guinea pig and start swapping parts...I know they are working on Blue, so I'll start swapping things over one-at-a-time until I find the problem.

1) Fuel Pressure Regulator
2) Cold Start
3) O2 Sensor

fuel pressure regulator is a good bet

Reviving an old thread, but the solution may help someone else. It appears to have been a faulty Coolant Temperature Sensor all along. I have been driving White for a couple weeks solid...have gotten good at the heel-toe brake and gas deal to keep her running. But noticed that cold mornings she was perfect until the engine warmed to normal operating temp. So, a $21 sensor and less than an hour install and all seems okay.

Man...now that you say that, it makes sense. We had the same issue at Harlan with Austin's YJ right after we finished the dash. The sensor was actually unplugged from where we had installed the sending unit for the new temp gauge. It was causing it to dump fuel like it was constantly cold starting. Plugged the sensor back in, hasn't had an issue since. Glad ya got it figured out Grant.
