The car runs very well in morning while going to office.
Smooth gear shifting, no misfire
The car stands in open the whole day and in evening while coming back, its doesn't run more than 100 kmph and gives jerks .
upon stopping the car and giving acceleration in neutral gear, it misfires,
I have changed
Spark Plugs, Coil, fuel pump but in vain.
pl suggest

How do I fix this problem? Also, the dash lights went out at the same time? Is there a linked fuse somewhere?

Check engine light came on a week ago and took to the shop and diagnostic test says it is the fuel pressure rail sensor. Wondering how dangerous it is to drive until I'm able to get it repaired?

Car sometimes delays when I start it. The diagnostic test says it is the fuel pressure rail sensor. That's why I'm wondering if the fuel injector is the same thing or something different than the fuel pressure sensor?

Where is this sensor located, and how hard is it to replace

My husband's 2005 Ford Focus check engine light came on and we had it analyzed by our local AutoZone who came up with OEM #P2004; Definition: intake manifold runner control stuck open bank 1; Explanation: ECM has commanded the IMRC closed but detects it open; Probable cause: 1) short circuit condition, 2) damaged IMRC actuator or solemoid, 3) blocked vacuum hoses. I have tried looking for this repair on several sites, but have not come across it yet. Any ideas? I would like to have an idea of how much money we are looking at to repair this. Many thanks!!!

the brakes are loud every time i touch them

I replaced the motor and fuse what else could it be?

The other day it came on again when I was slowing down in traffic and it stalled when I came to a stop. It did start up again but did this a total of 4 times during my drive. I had the battery checked and they said it was good. I also had the alternator tested and it showed that it was good as well. Is there anything else that could be causing this problem?

I was stopped at a red light and when the light turned green I stepped on the accelerator and it only got to half way through the intersection when it felt like something "dropped". The engine remained on and the car would not move in any gear (including reverse). The check engine light did not come on and there was no other noises or anything.

it has been happening for awhile

every time i start the car and i'm checked the gas cap

The guy at autozone said it seems there is a blocked vacuum hose. The code says IMRC is stuck open -- probable cause is Short circuit, damage to the IMRC, or blocked vacuum hose. The check engine light is staying on.

It started blinking tonight. I parked my car and shut the engine off. After I started it, the light went away. What does it mean and should I be worried?

Does anyone know the part # or where to buy them? I may just go to local junk yard. These cables plug into the Teperature control switch and run to the blend door.
