    have you tryed fuel injection cleaner? has fuel filter been changed ? does engine run smoothly except for accelleration?

  • tom reese Jul 20, 2008

    it could even be a dirty thorttle plate they sell a spray for this as well if there are no fault codes in the ecm you need to simplify a gas engine needs air fuel and spark until it codes do one minor fix at a time an occluded filter could be the culprit if it hasnt been changed recently its good preventitive maint.

When excellerating , seems to hesitate, then goes good, then feels like it is misfiring every couple miles or so.


it is missfire
and the CEL glows, and you scan it and get P030x. errors.
right?
first turn it up , then see if misfiring ends. that is first.
spending big cash diagnosing a non serviced car is over the top.

Hesitation when accelerating


If it does this only when warm then it may be the coil pack. To prove it you can warm the car's engine up and when the problem occurs, stop the engine and remove the coil pack. Place it in a bag if cool enough and place in the freezer, ensuring it can't get wet! Once cool, replace the coil pack and start the engine. If it's fine for a minute and then plays up, it's almost certainly the coil pack.

Have a 2004 CRV hesitates or jumps on excelleration code 2647 is what it reads. I have already changed the oil pressure switch but it is still doing the same thing. Any help would be appreciated.


P2647 VTEC oil pressure switch circuit high. The letter P stands for power train.When a code P2647 comes in the shop VTEC oil pressure switch usually fixes the problem. In front of the vehicle on the right hand side there is a VTEC solenoid valve one one the intake.Right next to it is the VTEC oil pressure switch . Both have grey connections. If you complain about rough idle then yes service solenoid (they do plug up from low end oil or lack of oil maintance).The code is circuit.that means that battery voltage has to be present. When the code P2647 appears VTC is disabled and valve timing is fixed at a fully ****** position.This is where you say you feel like its running out of gas is from.Switch is you just replaced it, a electrical diag has to be performed.From switch to PCM

Hesitation at 40mph and 50 mph.


A pop and hesitation is likely a backfire. The hesitation around 40 and 50 would be in keeping with that theory. There are several reasons you might be getting backfires and hesitation. If your ECM is adjusting the engine to run too rich this could happen. Misfiring might be occuring. Timing could be out. But one of the most likely is a restricted exhaust, likely due to a plugged, damaged or worn out catalytic converter. In some cases the converter may be bad enough to be giving you some performance problems, but not yet quite bad enough to signal an error. A vacuum test can help confirm whether this is exhaust related.
