Most likely coil issue, lack of spark would be just like lack of fuel.

I've got a 1996 jeep grand Cherokee with the 5.2 v8 fuel injected Holley throttle body. My problem is while driving at soft or low acceleration it accelerates fine, but if you hit the throttle hard it


I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.

Random multi miss fire, I have replaced MAF sensor, can shaft sensor, plugs, wires, fuel filter, I checked coils, I checked fuel presser; reset computer, cel keeps comming on for random multi miss fire,...


Some general thoughts - -
when you try to accelerate, a couple of things happen. The engine shifts sometimes, and you put it under a load unlike when it is idling.
Is it possible a wiring harness or a hose is moving when you accelerate ? Is it possible the fuel pressure or ignition module is not good enough to handle the engine under load ? Is the EGR opening early or something causing a vac leak and a lean fuel mixture ?

86 el camino stalls under load


As mentioned above, engine could be starving for fuel; but
also consider ignition system - as engine makes more power, maximum cylinder pressures increase. A higher spark voltage is then needed to ignite mixture (at a few degrees before top dead center... top of piston travel).
If coil is weak, plugs fouled, or plug gap too wide, adequate spark may not occur. This may cause missing,
loss of power, sometimes backfiring (backfiring may occur if timing is off, or intake valve leaky, also). If you replace the fuel filter, 'kit' the carb, but problem remains,
look to ignition system.

Diagnostic process - put a fuel pressure gauge in line, where fuel line enters carb. Rig so can see gauge, while driving. Have a passenger watch fuel pressure as you drive; especially while accelerating. If fuel pressure drops during acceleration, then its either fuel pump or filter. If pressure remains stable, consider carb issue.
If possible, test with exhaust gas analyzer, while engine
under load (possibly at an emissions test place). If lean under acceleration, its a carb problem. If not, look at
ignition system (emission test diagnostics should help here, also). Oh, and one thing I did once.... forgot to release parking brake..... duh.

Best of luck !

Acts like bad accelerator pump, but is fuel injected ?


THE FUEL INJECTERS HAVE FUEL FILTER SCREENS THEY GET PLUGED UP WITH DIRT RUST EXC... THIS GREATLLY RESTRICTS THE FUEL CAUSING A MISS AND RAPID HESATATIONS

1997 Dodge Dakota 3.9 slight acceleration like when starting out it misses like crazy replace temp sensor ,air charge sensor ,oxygen sensor in cad converter .crankshaft sensor and cam shaft sensor plugs...


check fuel pump pressure to see if it is getting the right pressure for fuel injectors and or fuel filter under driver's door on frame might have junk in it.

Why my motor miss during acceleration?


MISSING CAUSED BY MANY THINGS LIKE BAD SPARK PLUGS, WEAK IGNITION COILS.STOPPED UP FUEL FILTER OR FUEL INJECTORS.WEAK FUEL PUMP.CHECK FUEL PUMP PRESSURE SHOULD BE 44 - 50 PSI.LOW CYLINDER COMPRESSION CAUSE MISSING.

Truck misses under acceleration after it's warmed up.


that is a tricky one you have almost replaced everything. that is fuel injected if you dont have the right fuel pressure when you step on the gas it will fall on its face you need to take a fuel pressure reading and also it could be as simple as the fuel filter which is often over looked it could be cloged restricting the flow. also check the MAP sensor

Runs good until you accelerate then it lacks power it dont miss just alarge power loss in every gear if you let off of the gas its power comes back its about to drive me crazy please help? dwb


I would suggest changing the fuel filter. The engine seems to be starving for fuel and if the filter is pulgged, the engine will bog down under load. Then the engine will run better when coasting because the fuel pressure will build up again.

I have a 2001 Nissan Sentra 1.8se and I am having problems getting my car to start. When I do it will not accelerate properly. It misses really bad. I have replaced the computer, the mass airflow sensor,...


Check the fuel filter. Do keep in mind that the fuel system is 'always' under pressure!!! Also check EGR. Your fuel pump must be working or it wouldn't start at all. The C02 sensor could be part of the prob. A real bugga to change! But should be changed every year. Do start with the filter, then move on. You have spent enough already! Frankster016
