SOURCE: stops accelerating and check engine light comes on

The check engine light indicates a fault in the engine management systems. Your car has stopped accelerating because it is locked in fail safe mode and normally you should be able to accelerate just enough to limp to the dealer where they wil scan the computer.
Cheers.

SOURCE: rough idle / varying oil pressure when accelerating

Ok not to keen on newer vehicles actually prefer the carburated ones, but oil pressure is supposed increase on your gauge when accelerating. If it wasn't going up before and just staying at 40 the needle might have been stuck. But idle should be 40 lbs and when you work the moter (reving or driving down the road) the guage should show an increase for every 1000 rpm above idle. Second if you can get a hand held scanner (bought mine off ebay for $30) check for any codes in your computer you will probably find that you either have a bank running wrong or some other sensor that needs to be changed. I'd go with getting my own scanner it saves alot of money and time, garages make their money here.

SOURCE: 1999 Nissan Altima - Whining Sounds When Accelerating

Well, not sure if the temps have a direct cause for your problem, but you may want to check the CV joints on your axles. If you have ripped a boot, and lost the grease, that could cause a whinning. There are also a few other things it could be as well............any more info?

SOURCE: Rattling sound when accelerating on 2007 Forester

On mine, I got under there and there are rocks rattling in the heat shield. There are factory made holes in it, and the rocks sit in there like eggs in a carton and rattle when the engine hits a certain vibration frequency which is basically when it is at a stop light or idling. The repair shop wanted to charge to cut them off but I think I am going to drill bigger holes so the rocks fall out, as they are pretty tiny.

SOURCE: A/C blower stops blowing air on acceleration

Its is not just a leak, it is the main vac line for the AC door that directs the air from the floor, vent, and dash. If you can find that line put a one way valve in it.( i think they run about $1.50 and the parts house) That should stop the problem of loosing vac at higher rpm.

Tapping sound when I start the car which gets louder with acceleration


This may be a pulley or somthing that is running with the start of your engine. If its a tapping sound that gets louder as you accelerate, that is usually a valve noise or somthing internally. This is a very bad thing if the noise is comeing from the engine inside under the valve cover. If thats the case then check the oil level and take it quickly to an auto repair shop for a diagnosis. Another culprit as mentioned in the beggining is a pulley that is either loose or out of round, whick does not cost to much to replace.

Hope this Helps!

Engine taps when accelerating, let off gas and it


HOPE IT'S NOT PISTON SLAP, IF LACK OF MAINTANENCE WAS THE CASE MAY BE INTERNAL DAMAGE OR VALVETRAIN DAMAGE. IF IT RUNS ROUGH MAYBE SOMETHING ON ROTATING ASSY DAMAGED.

Nissan Installed throttle reprogram


Here is the way to do it without the nissan scan tool. Make sure to follow all steps and it it best if you use a watch with a second hand.
1. Perform "Accelerator Pedal Released Position Learning".
a. Make sure that accelerator pedal is fully released.
b. Turn ignition switch 'ON' and wait at least 2 seconds.
c. Turn ignition switch 'OFF' wait at least 10 seconds.
d. Turn ignition switch 'ON' and wait at least 2 seconds.
e. Turn ignition switch 'OFF' wait at least 10 seconds.
2. Perform "Throttle Valve Closed Position Learning" .
a. Make sure that accelerator pedal is fully released.
b. Turn ignition switch 'ON'.
c. Turn ignition switch 'OFF' wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound. 3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic 'PREPARATION' (previously mentioned) are in good order.
5. Turn ignition switch 'OFF' and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch 'ON' and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal. 8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MIL goes off.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
13. If idle speed and ignition timing are not within the specification, the result will be incomplete. In this case, more test needs to be done.

Stops while driving


this is usually due to a dirty throttle body. just beware if you do try to clean it you will need to preform the idle relearn procedure. this does work, ive done it personally.

A. Accelerator Pedal Release Position Learning Procedure.
1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds (how would you know if you get it right?)


B. Throttle Valve Closed Position Learning
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is “ON”.
3. Turn ignition switch is “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound (i never get this right because i never heard anything)

C. Idle Air Volume Learning (Throttle Position Learning)
It's best to time with a watch/clock.

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops
blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11 Wait 20 seconds
12Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications. (this is fine because SES light lets you know if you did it right the way it blinks)

Blowing efi fuse


carman963, OK, It sounds like you have a lead wire that is getting grounded out only under acceleration, check all of the wiring running to the engine from the master relay panel and examine any wire or connector that passes within 1 inch of any metal, look for signs of any arcing. Try this first and then get back with me with the results. Good Luck, quicbric
