Can an 2005 acura run safely on regular gas


The only reason to run higher octane fuels to to reduce the chance of (engine ping) or (engine knock).Try the regular gas(dont completely fill car) and take notice under hard acceleration if engine makes a pinging noise.If pinging happens then add some high octane gas to compensate for regular.Unless this is a modified engine the regular gas will not do any damage it will result in pinging and loss of fuel milelage.

I have a 2002 vw jetta tdi diesel, the engine lite keeps coming on usually on a hill, but not always. sometimes it goes ou. i hooked up a code reader and code po234, overboost came up. what do I need to...


Boost is controlled by the N75 solenoid with vac' hoses to the vane controller built into the turbo.

When light comes on it indicates too much boost and will reduce fuel delivery to reduce power.
A '' key off/key on'' cycle will reset it if you on the road.

When an over boost occurs it is best to first change the N75 Solenoid Valve and or check the hoses from and to it for displacement or splits.

Before removing the valve, make a note of where the hoses fit.

Common component failure.

Jetta 2006 tdi highline i bought 6 months ago i thought is a good car but now i can see black smoke and lost power i send to garage and the mecanic work somthing on timing he say here is 2.5 and i will...


Black smoke from the tail pipe means the engine is not getting any air like a dirty air filter. I think your mechanic is telling you is that you need a new turbo. The turbo boost incoming air pressure to the engine and if it is bad then it will not let enough air into the engine causing black smoke from the tail pipe.

I have a 2002 vw jetta tdi there is a warning light that is almost always blinking it looks like a coolant or temp indicator but not sure i have no manual also sometimes the car has no power what so ever...


this could very well be the coolant resevoir/level sensor. if it is running poorly, these engines have a big tendency to foul up the throttle body and go from a 3" hole to about 1 1/2". if you take off the air horn to the throttle body and look inside you will be able to see what im talking about. now you can chip away at it but it must be done very carefully. dont let any fall down the intake. the proper way is to remove the manifold and let it soak. the egr is attatched to the throttle body and this is the reason for the carbon build up. also check your fuel filter. after this, it runs like a new car.

At what millage should i change the automatic transmission fluid? The car is shaking when i put it in drive it dosnt shake when is in parking i need to put it in neutro everytime i stop in a light so it...


around 75,000 miles, plus or minus 15,000 or so. when you say shaking, do you mean a rough idle? thats not cause by your transmission per se...

Sounds more like a weak fuel pump, idle controller, or well, theres a bunch of reasons you could have a rough idle.
