My car is shaking and i wonder if i could use fuel cleaner to stop the shaking and rough idling when at a stop

Question

it is a toyota previa 91 i need help plz

Answer 1

Get a tune up on the car.

Answer 2

Its a good idea to regularly use an injector cleaner anyway. Although it may not work, its worth a try for what a couple of cans cost. Get your hands on some Sea Foam. Put two cans in a full tank. A tune up may not fix injector problem.
As far as the shaking thing goes, if shaking occurs while driving and not idling, could be you need to get your tires balanced or simply replaced if they are old.
Funny how mechanics will tell you to spend a lot of money instead of offering you a suggestion that might help.

Answer 3

A fuel cleaner probly won't help, and don't just "tune it up" and waste money when it might not fix it. Exactly what kind of rough idling: rolling idle, low&rough? It could very well be a sensor or vacuum leak small enough that it would only be apparent at idle and under acceleration the problem may be masked by the extra fuel.

Answer 4

i own a repair shop,and if you knew for sure that the shaking was caused by the fuel injectors it might help it,but it might just need a good tune up,like a good set of plugs and wires on it,so really it cant hurt to add the cleaner to it,but that doesn't mean it is going to help it either,you might want to consider having a real good tune up done on it,they usually cover all this stuff,and that will probably stop the shaking in it,good luck with it hope this helps.

Answer 5

A fuel cleaner won't hurt, but use it concentrated, IE less than a quarter of a tank for maximum effect. If carburetor spray cleaner down the throat of the carb. But it sounds like you need a major tune up, IE platinum plugs, cap and rotor new wires, and check all vacuum lines for leaks, don't forget to change the PCV valve, seems to be starving for air plus the air filter.

Answer 6

seems such as you ought to apply a song as much as get rid of the tough idle, yet for valuable, till each little thing on the engine is desperate to unique specs , you somewhat won't be able to confirm what's the undertaking. gas cleaners might help extremely however the song up will confirm different issues.

You should probably get a tune up, the fuel cleaner wont hurt, but it might not help. You also might waant to check the axels.

Answer 8

A wire may be resting on the HOT manifold when your at a red light and causing a small short to take place as your wires are relaxing and resting on the HOT surface.

Also usually means it's time for new wires. Spark Plugs wires are cheap and so are spark plugs.
