SOURCE: no power when accelerating

Once you rule out some kind of ignition problems,; spark plugs and wires, ignition timing, distrib. cap & rotor, the cause may be low fuel pressure from a failing pump or clogged filter. Listen to the pump in the gas tank. If its been getting louder lately, have the pressure tested.

Vacuume Leaks can cause this problems. you have to do a through check of vacuum hoses and the EGR valve. Your best bet can be to have your vehicle scanned at an autozone store and get a code. The EGR has to be closed at idle, then as the engine warms up or is accelerated, the EGR opens. That is if your car does not have an electronic EGR . The electronic EGRs do not use vacuum to operate. They are controlled by the PCM (power train control Module).

Could be a short in the wiring for the O2 sensor.   I currently have the same issue only my car finally threw a code after two days of it acting up.  Code 106.  Changed the MAP sensor and it now throws 108, MAP sensor high voltage circuit.  Ah the joys of cold weather and broke down vehicles.  But I know that you wont always get a code with a short.  Let me know if you fixed the problem.

SOURCE: 1997 ram 1500 5.9 wont rev past 2000 rpm

well, the timing on your ram is computer controlled. is the truck in drive when this mis-fire occurs? or at idle? youve addressed part of your ignition w/the cap-rotor-plug wires. did you examine the old cap for carbon tracking? did you install the rotor properly? i know on my '97 ram the dist is feakin' buried in the engine it would be easy to rotate the rotor while installing/removing it so the timing mark is off. does your engine have the right plugs installed? your plug wires follow the correct firing order with your dist? you did not mention anything about your ignition coil. here is how to safely remove and check your ignition coil. disconnect battery-at the coil disconnect the lead wire (TOP) and primary (BOTTOM) from the coil. label your wires, or take a pic of your ign coil before you remove it so if you forget where the wires go, you have reference point. remove mounting screws and remove coil. clean coil to remove rust/dirt and wipe coil terminals off. inspect case for damage. with a multi-meter, check coil primary resistance by selecting ohm's and then place + and - leads on the pos/neg terminals on the coil, dodge used 2 brands of coils either a "diamond" or a "denso" primary resistance for the diamond mfr'd coil will be between 0.97-1.18 ohms. secondary resistance 11,300-15,300 ohms. Denso primary resistance 0.95-1.20 secondary resistance of 11,300-13,300 ohms. to measure secondary resistance place one of the leads to one the primary terminals and the other lead attatch to the large center terminal. compare your readings to the above values. if your readings are not within range of the above values, your problem is the ignition coil. other causes you may consider is faulty: speed sensor, throttle pos sensor/trans issues like bad pressure solenoid (actuates gear changes) a fault in your overdrive system. hope i have helped!

You may have got a slug of water in the gas, try some additive and see if it will clear up. If it dosent best do a fuel pressure test, i don't know why but pumps have been known to go out just after a fill up.

Whens the last time you change your fuel filter. The other problem could be the fuel pump. Our you using Bio Diesel or regular Diesel ?
Some Bio Diesel will not burn hot enough to give you the power.

89 nissan maxima stalls out and will not run past 2000 rpm


I'm not a mechanic and I know this is an old post but I have the same car and in my research trying to figure out what's wrong with mine I have found in several posts that the MAF Sensor is bad because if it is bad the cars computer will NOT let it go past 2000 rpm's. When I saw that number in your post I KNEW that was the answer.

Have a 4M41 engine in the 2007 mitsubishi triton and when under acceleration between 2000 - 2600 rpm the engine hunts or surges and then clears after 2600 rpm. It is more noticeable in 3/4/5 gears only...


It needs a programming check of the accelerator pedal via ecu of the engine. All previous activity of the system is recorded in the ecu which can be corrected in the dealership of mitsubishi.
