First thing you should do it take it to a Ford dealership and tell them of your lack of power concern. They have been known to have fuel pump problems, low fuel presure causing lack of power. There may be an extended coverage recall on your vehicle that you cover the replacement of the fuel pump.

Where do find the vapor lock on my 1999 Buick century


Vapor lock occurs when the gas in a fuel line turns from liquid to vapor, before it reaches the engine. The first signs of vapor lock are normally when your engine begins to run roughly. The engine may sputter and hesitate. It will then stall completely and refuse to restart. It may seem like the car is out of gas or the fuel pump has failed. While these are possibilities, vapor lock may be the problem.

Why does fuel vaporlocks after warm?


Gasoline has what is called low vapor pressure, in English that means it evaporates very quickly, most people know this. The vapor lock is when there is only vaporized gas in the fuel line, it has to purge out just like air before liquid fuel reaches the engine and that is called "vapor Lock". You can wrapping the fuel line to insulate it from engine heat, that may help.

Why is my 1993 mercedes benz300e hard to start when engine reaches normal running temp.


This is a fairly common problem with naturally-aspirated engines as they age, because the oxygen sensors become contaminated and do not operate as effectively, plus the idle air controls become sluggish in their operation and fail to adjust quickly enough. If the CHECK ENGINE light is on, check the codes, and most likely you will find that one or more of the oxygen sensors are at fault.

Try starting the car while holding the throttle at 1/3 to 1/2 until it starts. If it starts more easily that way, do that each time you start the car when it's warm. Replacing the oxygen sensors and the idle air control will solve the problem but part-throttle starting will save time and money in the meantime if the trick works.

Sluggish ignition start


I think your mistaken. Your battery will lose cranking power as the temp drops. Warm battery may work just fine, untill it gets below freezing temps then the cranking amps are so low its sluggish. Buy a high cranking amp battery and you will be good as gold mate!

98 and 99 intrepid was manufactured with weak fuel pumps causing them to vapor lock try pouring cool water on the fuel rails on the intake to calm vapored gas then try to start it. Even the temp gauge at half way mark is probably still low on coolant causing engine to be warmer than normal causing the vapor lock to fix this problem replace the fuel pump with a 2000 or newer intrepid fuel pump that carries a little higher psi to prevent vapor lock from reoccurring this pump is compatible with your 98 it will plug right in

99 rodeo starts hard after is has been warmed up. Starts fine after it has been sitting overnight. Almost starts like it is flooded. Have changed O2 sensors, coolant temp sensor. Cleaned IAC


Hello, I usually work on Ford family Brands. There are sometimes 2 temperature sensors on engines. One is meant for the dash gauge alone and the other is for the Engine management systems.

You could have one of several problems. A starter can sometimes fail becauseof heat. You would need to do a draw test when the motor has been run to duplicate your problem. Autozone, Advance, and Oreillys are some of the free test places.

The cold start cycle is like an Electronic choke. If the temperature info is not reaching the Engine management controls then the vehicle will always be set for a cold start.

Lean conditions also can lock an engine. In order to get good mileage the Camshaft timing is advanced. If the engine has worn timing parts, the firing may advance beyond specs. You may be fighting compression and experiencing vapor lock. Try going up a Grade in gas Octane.

1995 olds cutlass ciera 3.1 V-6 stalls when warm


Some times the fuel line may be too close to the exhaust manifold or engine and can create a condition called vapor lock. This is where the fuel is heated to a vapor in the fuel line. This is easily corrected by just moving the fuel line away from the source of the heat.

Intermitant temperature


Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
