If your car is fuel injected, the electronic throttle position sensor on the throttle body could be bad. The check engine light doesn't always come on, in this situation.
AnswerWell it kind of depends on how new the car is. If it's a newer one or your lights start to go dim as one person put it, it is quite simply the governor. Fairly cheap and easy to have that problem fixed. If it's an older vehicle read some of the answers below, they're pretty accurate, although one other thing it could be is a blocked catalytic converter.
AnswerI had the same problem with my van, after many misdiagnosed repairs it turned out to be that the 02 censor was not working properly, have that checked.
AnswerI surprised myself and resolved this problem on mine: Too much dirt, etc built up in in line fuel filter. As I accelerated larger demand for fuel caused blockage and starved off motor.
Check the little things first!
AnswerI have the same problem but not the answer.
But I have just realized that when it happens the driving lights go dim.
Bog When AcceleratingI had this same problem with my 1988 Chevy S10 Blazer 4.3L This could be a problem with your EGR circuit. This circuit stand for exhaust gas recirculation and is responsible for moving a little exhaust gas back into the engine for combustion. If your vehicle is newer than 1973 it is required to have this device in it because it reduces NO2 emissions. Replace the EGR valve and solenoid (valve first because it is more likely to be the issue). They are both fairly inexpensive parts (mine was about $110 for both) and they are easy to replace. You don't even need a mechanic for this fix. If you try this and it doesn't work, put your old parts back on, return the new ones and try replacing the throttle position sensor if you have a fuel injected model. Hope this helps.That all depends if its a carbureted model or a fuel injected model. Carbureted model has an easy answer. You have a dead spot in the carb. you can do 1 of 2 things. Rebuild your old carb or buy a new one. Generally the float is just sticking. With fuel injected cars when you have a problem like that the check engine light should come on.
If it has a distributor, check to see that the weights under the rotor are free moving. If they stick, then the timing will be slow to advance and the engine will bog for a second or two.
MY WAGON WILL BEAT A LS1
JMHO:
Any of the above could be true. It also could be carbon build up in the intake lines, valves, & carb (if there is one.) If this is the case, a fuel intake cleaner will clear it out and a new fuel filter will also help. Carbon does the same thing to those components as cholesterol does in your arteries.
Good luck!
Just had this problem with a 350z. The car was cutting off at 5k rpms, then gradually got worst and started cutting off at 2500 rpms. Turned out it was a bad MAF sensor. I replaced mine at a very costly price! I would suggest (If applicable), clean your MAF sensor. You can buy the cleaner at autozone. Doesnt hurt to try!
If an engine loses power on and off on a Honda Spreeline the alternator may be malfunctioning. The unit should be tested for voltage to see if it is providing enough power to keep the vehicle running.
could be two things. if it does it while idling or accelerating, then its probably a spark plug not firing. if it only does it while accelerating or under load. then its probably a spark plug wire. either way, as general maintenance its a good idea to replace all the wires and plugs. Clogged catalitic converter will cause it to lose power.
dirty fuel filters for one !!
If no codes (check engine light) or rpm fluctation first check fuel pressure
If you have a loose spark plug, your car will not stall unless maybe your engine has 3 cylinders. If you have a 6 or 8 cylinder engine you would just loose some power and your engine would run a little rough.
The computer turns the AC clutch off when accelerating for maximum engine power. The AC compressor uses up some engine horse power.
Engine will loose power, engine sputters or stops running, GAS GAGE SAYS EMPTY
The most common cause for a lack of power whilst accelerating is a clogged exhaust system or lack of sufficient fuel being delivered to the engine. Check your catalytic converter if your vehicle has one, and then change your fuel filter and go from there.
No, it does not loose power but when the engine is cold, it is just harder to turn over.
Power steering like all other accessories tax the 'power' of the engine; if there is a problem in the power steering causing excessive load on the engine it will loose power (more so in low horsepower engines).
There are a few ways you can tell if you have a bad fuel pump. These are is the engine sputters at high speeds, vehicle loses power while accelerating, or the engine will not start.
Loose battery cable much?
