Do u have a check engine light coming on? if not the plugs are not the problem a miss will trigger a check engine/service engine soon light, most likely you have a dirty automatic idle speed control motor.

I would be looking for a vacumn hose leaking. The cold engine needs a rich mixture and braking uses the vacumn booster causing the mixure to lean. A warm engine races with the extra air.

1993 jeep grand cherokee loses power at operating temp.


ever do a real tuneup this decade
spark parts, and filters. that be first
and make sure the hot engine (sized not stated) is really hot.
180F or more, and holds, it must reach normal spec, temp.
or the ECU brain will not do its job right.
the only clue I have here is skips
skips must mean misfire.
there are over 50 causes of misfire.
bad spark plugs tops the list.
and all spark parts there, cap/rotor,wires set this OLD.
car is old , needs a major tuneup

they to forget all that other stuff, and elaborage
what skips means.
i guess never cold does it skip.

I got a 1988 mercury grand marquis LS that just about stalls when you drive it cold and put it into park. Cold meaning the oil is cold not the weather.


it doesent mean the weather it works the same if the engine hasent been rann for awhile its not at operating temp try running it till it reaches normal temp if it does not stall its your cold oxigen sensor

2000 maxima has erratic idle on cold days and will stall out on extremely cold days. Also, have noted antifreeze leak (on ground) on those really cold days. Car runs fine once it reaches normal operating...


It sounds like an engine temp sensor is open.. When your engine is cold or anti-freeze is cold your ECU or ECM gets a signal from the temp sensor for cold engine start. It would make sense that it works fine when hot because the resistance on the sensor is a lot lower. Take an ohm meter if you have one and check the resistance across the temp sensor pins. When the engine is cold the resisitance should be really high. Start and warm up your car to normal temp and check it again. It should be a lot lower now. If not replace it. Hope this helps.

Bucking/stalling in cold/damp


check you thermostat because it maybe stick on open so your engine is running cold and cant reach the required temp.

Very bad idol and run condition.


sounds like a possible water temp issue... check your thermostat and/or water temp sensor. when you first start your engine the computer uses the water temp reading to do a 'cold start' scenario, more fuel. once you reach normal operating temp the fuel should be cut back. if the thermostat is not opening and closing properly this can cause strange readings from the water temp sensor (which is mounted near the thermostat)... unlikely the sensor is bad, but a possibility... more likely the thermostat.

Oil pressure high when engine cold. but fine when engine is warm


It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.
