Gas smell
Posted: Wed May 20, 2015 12:24 pm
Hi ppl,
Please, need some help. My main concerns are the gas smell and some funny behaviour while in idle.
** When the engine is cold, I have to hold the ignition key at start position for 6 or 7 seconds. In this case, before the engine starts, the car shakes, like it wants to shut off. Sometimes I need to depress the gas pedal.
** When the engine is warm, it starts normally but the tach needle goes to 2,000 - 2,200 RPM then falls to 1,200 or 1,000.
** When I drive the car at normal speeds and want to brake to 0 MPH, I use to depress the shift pedal and shift to neutral position. So I only need to press the brake until the car stops completely. In this case, the RPM falls to 1500 while the car decreases the speed. But in case the car is still moving and I only depress the shift pedal, the RPM increases to 1800 then falls to 1500. When the car stops, the RPM slows to 950 - 1000 RPM.
** From 0 MPH, at first gear and starting to accelerate the RPM decreases to 700 and increases again, then it goes increasing normally while
>> The fuel consumption is around 18 MPG combined (high traffic). I use 90 octane fuel. When I put 95 octane, it improves a bit.
>> The fan turns on before the temp reaches the middle point of the dial. It's around 2/5 of the dial.
>> The oil pressure when the engine is cold is above the middle point, once the engine is warm it starts to fall. When I depress the gas, the pressure increases, but never passes the middle point. At lights, the pressure is around 9 - 10 PSI.
>> No SES lights (it works). Anyway, trying to fix the gas smell and the idle problems, I've replaced the MAF sensor (3 months ago), the IAC (1 week ago), the CKP (it died 2 months ago) and the fuel pump (it died 2 months ago)
>> The car never shuts off, it only shakes a bit. Runs fine. At idle speed and normal temps, the RPM is 950 to 1000.
>> When installing the MAF sensor, I noticed the sticker about the ECU reflash... so after making some research, I think that I wasted my money with this part...
I'm planning to replace the O2 sensor, but don't know if it will fix the problems. What do you think?
Thanks in advance.
