Service Engine Light and no accelerating power

[asimrauf]

Anyone knows or experienced similar issue. Just today I got service engine soon light. I filled up gas 87 octane yesterday and last time it was a just a loose cap that caused this light to be on. However today I also noticed the significant difference in acceleration. The truck is not very responsive when accelerator is pressed. It takes about 2 seconds before it moves and acceleration is very slow. I also noticed the engine pressure gauge stays towards L instead of in the middle on the scale when truck is idle or at low speed. Has anyone experienced this issue?

low oil pressure reading on the gauge is caused one of 2 things

1: disconnected oil pressure sensor wire or damaged sensor.2: There really is low oil pressure and you have some serious issues. Things that cause low oil pressure: bad engine bearings, oil pump failure, low oil level,

Since your check engine light is on you really should get the code scanned and interpretted so you can fix the problem properly. And I recommend you do it ASAP.

Thanks! I am taking the truck to Nissan dealer tomorrow.I am hoping its the sensor. Will post results for others what I found and what was the resolution.

It's not terribly unusual for oil presure to be lower at idle. Most parts chains will read the codes for you when you have the SES light on. It sounds to me like either a throttle position sensor or MAF, but it's hard to tell without the codes.
