#296 of 460 Spark noise under pickup by colours Aug 06, 2006 (8:21 pm)
Hi. I have been hearing a spark-like noise coming from under my 92 Nissan truck. It's automatic, 4 cylindar, has a converter. I've had the brakes, muffler, left tie rod end, and the bushings on both sway bars in the front replaced, and a wheel alignment done 2 weeks ago. this sound is new since the alignment. It only happens when I step on the gas pedal. As soon as I release my foot from the pedal, the sounds disappears. The sound does not happen every time I step on the gas but 90% of the time. This spark like sound is becoming louder as time goes on, and it does not appear to be a body caused sound.   Can you help?   Thanks

#298 of 460 Decreased mpg in 1993 Nissan Pickup by tony1958 Aug 23, 2006 (6:42 pm)
Replying to: asa (May 28, 2006 5:52 am) I have 1993 Nissan Kingcab SE V6 4x4 pickup with 220,000 miles on it, and still like it, of course. Been taken care of reasonably well--regular tune-ups, oil changes, and all PM. About 50,000 miles ago the mileage went from 21 mpg to 17.5 mpg and has stayed there. Occasionally it would bounce back up, but not for long. With gas prices continually climbing, I'd like to get it back to over 20 mpg. I've taken the car to the dealer who confirms by some test that it's running rich. He suggested changing the oxygen sensor, but I did that 30,000 miles earlier and it didn't help. I also recently had the thermostat replaced thinking it might be the cause. It didn't help either. I'm not sure what to try now to get the mpg back up. Anyone have any ideas?

Replying to: tony1958 (Aug 23, 2006 6:42 pm) In case this helps... I had a similar problem on my 1988 Mazda 323. In my case, the problem was with the fuel pressure regulator in the fuel injection system.   The pressure regulator had failed and the excess fuel pressure from the pump was not been diverted back to the tank. When I measured the fuel pressure, I read 70psi while about 35-40psi was the normal. So this increased fuel pressure caused excessive fuel to be injected every time the computer pulsed the fuel injectors. The computer was probably seeing the mixture being too rich and was thus shortening the pulse to the injectors but apparently with a 70psi fuel pressure even a short pulse was already delivering too much fuel. The computer would sometimes give me an error code for bad oxugen sensor. Do you get any error codes (engine check light)?   In my case when I replaced the fuel pressure regulator everything was fine and my mileage went back up to 37mpg (it had fallen to 22mpg).   So I suggest you measure your fuel pressure to see if it is within spec. If I can remember well I bought a fuel pressure meter for just under $40 a couple of years ago.

#301 of 460 1998 XE - "Clattering" sounds... by gkolman Sep 13, 2006 (9:31 pm)
I have a 1998 Frontier XE, 4 Cyl, Manual Transmission. I have started to hear a "clatter" sound when starting to drive, especially when in 2nd gear. Kinda sounds like a thin chain clattering against metal. I've noticed no jerking, hesitation, or power loss when driving, just the noise. Was thinking it might be the clutch or transmission, but not sure. Anyone have any ideas? Thanks Replies to this message: moneyman6 (Sep 16, 2006 9:30 pm)

Replying to: tony1958 (Aug 23, 2006 6:42 pm) I have a 2001 Nissan Frontier 3.3L S/C; adding a cold air intake gives around 4 mpg and an intercooler can give up to ten mpg. Also after adding cyclone's mpg improver I was getting about 26-28 mpg. I run my engine on full synthetic high torque/high RPM engine oil and have enjoyed the effects. I have done some minor exhaust work and my mileage went down accordingly, along with working on the headers. I am adding an underglow kit here soon when I get the money for it, but with the performance mods my mileage has dropped to 21 or so. Then again I also tuned up the supercharger which close to doubled the output when I changed the throttle body (also adding a throttle body spacer -- which should increase gas about mileage 2 mpg) chandeg out the Air Pressure Reg. and the S/C fan. And probably a week ago I changed out the gearing from the belt to the S/C and am greatly impressed with the output.... though I am nervous about gas mileage.

Replying to: gkolman (Sep 13, 2006 9:31 pm) Add a SMALL amount of water to the clutch and drive for the ussual span of time when you hear the noise. the water should add enough lube to the clutch that you will no longer hear the noise... at least for that short period of time. If you do not hear it like you ussually do it is probably the clutch, which you can replace at little cost, or you could add a faster engaging clutch which could increase gas mileage and faster engagement with less stutter. good luck.
