about a month ago I had the same or similar problem.

to day wife had to go to the air port to take her sister to catch a plane,
about a 3 hr drive to the air port, and 3 hr home,

air temp about 0,

when I fueled it up, it died on me once, Then I parked it in the shop over night, over night went down and brought up the car and left it running while they loaded there stuff in it, , it died again,

she said it ran fine the first 6 miles, and then it missed some or cut out for about 1/2 second and keep running, and would go about 10 miles and do it again, and she said it was getting worse on the way home, she thought that driving under 45 it did not do it,

but it does not give one confidence when it is 0 and below out, and we live in a area where one can go many miles with out meeting another car,

~~~~~~~~~~~~~~~~~~~

last time I changed the fuel filter, and check pressure it was OK,

new plugs and wires, new coils, new spark controller, new crank shaft sensor,
cleaned the MAF sensor. no check engine lights,
it appeared to be running great, and now about month later,
it is acting up again,
~~~~~~~~~~~~~~~~~~~~~~~~
(the keeping it under 45 mph has me some what puzzled, unless the fuel pump is crapping out,
(the crank position sensor seemed to fix it last time)
but appears to be the same problem? again. at least ti is similar.


Any ideas? all I did was take it for a drive about 6 miles above 55, and did not have a problem. I really do not even know were to start and since it is not consistent.

where would you start?

Basics...

Are you losing coolant?

If worried about temp, try some dry gas in the tank.......

How long ago did you change the fuel filter?

Unfortunately, you may have to drive with a fuel gage attached to monitor pressure when the vehicle acts up....

Could be an ECM, try a tap test....

Also check wiring....make sure battery cables are clean and tight......with car at normal operating temp, start pulling on harnesses in the engine compartment to see if you can get a reaction from the engine....

for ha-ha'*, check for codes using the flash technique if you don't have a scanner/code reader...

the fuel filter was changed about 30 days ago, and the old one was not "bad",

it has ethanol in the gas from the pump, can't get any thing else here,
which is the same thing as gas dryer,

will probably do a pressure, and volume test on the pump, tomorrow,

no coolant loss

fuel pumps tend to go in the cold, if its old. is the shop heated? should be able to do the pressure test like tech 2 said. if you step on it and the pressure cant keep up thats probably it

it appears to be the Ignition Control Module,
I replaced it and the car has not had it miss fire since,
