When accelorating rpms and engine get stuck

When I press the accelorator I can feel my truck try to gain speed but it's as if it get's stuck. The rpm will reach the 4 and stop and it takes a moment to kick into gear. The engine smells hot afterward. Does this daily and was worse on the highway.

Sounds like itr is not getting enough fuel. Try or check the fuel filter for dirt or water, and also check the fuel pump pressure to see if it meet factory specs.
Good Luck Jerry

SOURCE: engine misfire or flat spot when accelorating put occasionally

the camshaft position sensor is right around the crankshaft. there is a magnetic wheel at the end of the camshaft that the sensor uses to produce the signal.

SOURCE: Check engine light is on, not good acceloration

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The computer detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds.
You will likely not notice any serious drivability problems, although there may be symptoms.
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

  • Inspect for the following conditions:
    An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components:
    - The secondary ignition wires or coils
    - Any solenoids
    - Any relays
    - Any motors
  • A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
  • A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
  • When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude.
  • A high resistance on the ground circuit of the MAP sensor can cause this DTC to set.
  • Any loss of vacuum to the MAP sensor can cause this DTC to set.

Check the engine codes at Autozone or a place like that. Then check fuel pressure, change fuel filter, and listen for hissing when you remove the gas cap, from a possible bad purge valve.
Final advice is to try a slightly smaller spark plug gap, because it will not blow out the spark as easily when under load.

SOURCE: 2003 chevy Suburban. Transmission is slipping as

if the transmission fluid level is fine, and the fluid doesnt look black, or smell burnt, id say you need a new seal in the front pump, or possibly a preasure solenoid. Id have it scanned by like autozone or someplace like that, and see if its throwing a code.... either way it sounds like a pressure issue.

My 2010 Honda Civic started fine this am. The check engine light was on. The only forward motion I could gain was from the engine, pressing the accelorator made no difference. It ran fine yesterday


If your check engine light is on then there is something not functioning the way its meant to.give the car time to warm up for awhile and then switch the car off for a few minutes. Restart the car,your check lights should come on a go off after its checks. Try that and see if it works out. Good luck.
