Will start when cold but not when warm

My 1998 mercury mystiuqe will start just fine when its cold but after you have driven it and its warmed up it wont restart untill it is allowed to sit for a wile and cool down. I have been told it has a bad o2 sensor but I don't know wich one it is. The car seems to surge at about 35 mile an hour. I figured the surging was from the bad o2 sensor I just dont know if that is what is cousing the starting problem to. Thank you for you help.

1997 Villager gas smell when outside temperatures are hot and vehicle has been driven.


A common problem with Nissan products, which this van is a Nissan Quest with Mercury trim.
There are several small rubber fuel hoses around the intake. When the air temp is cold these hoses can leak and then stop leaking when the air temp warms up.
When the air temp is cold, look around the intake with the engine running and you should see one of the hoses wet with fuel.
Just tighten the clamp.

you need a transmission fluid and filter changed.because if filter stopped up.transmission fluid little thicker in cold climate make it hard circulate through filter.when engine and fluid get warmer fluid get thinner where it can circulate through filter cause transmission to shift correctly.

Car runs fine cold warms up starts missing


well either the ignition timing or fuel choke/enrichment needs to be adjusted as it is not changing in respect to the engine warming up. someone who knows what they are doing needs to take a look at it.

My 1998 Mercury Sable will idle around 2500 rpm after it is warmed up and has been driven for awhile, It is more common in the summer than in the winter.


sounds like it needs a good service . the air filter could be blocked there could be vacuum hose problems or the throttle body could be dirty hope this helps
