Could be a weak head gasket. White smoke is usually coolant burning.

SOURCE: no power uphill

"Loss in power" usually means that the combustion chamber in your cars engine is full of carbon. That is left behind because of the unburned fuel. With that type of problem, fuel responses will be slower, poor acceleration, lower rpm, etc. You may overhaul your engine for them to clean the carbon manually, but it'll be expensive and could lead to "loose compression". That means the engine won't be as powerful or responsive as before.

The best way would be to have a carbon ridding solution injected into the engine. The solution will liquify the carbon and other build-ups, which would then restore the "power" of your car. You'll get better acceleration, higher rpm and top speed, etc. have a mechanic do it for you. It's alot cheaper and faster than having the engined overhauled.

SOURCE: 1999 hyundai elantra transmition shifts from first

Hi willie what you might want to try is pluse generators. these sensors send signal of the input and output speed of your trans and cause the trans to not shift from 2nd to 3rd and sometimes overrdrive. The 99 00 elantras are known to do this due to these sensors not working. hope i was a help.

White smoke or semi white can be produced in several ways. One way is oil this is normally a whitish blue to blue smoke and has the apparent smell of oil being burned. Next could be antifreeze when it is being burned it has a sweet type of smell and tends to dissipate in the air rather quickly and usually is because of a bad head gasket. Next is automatic transmission fluid which is normally found on automatic transmissions and its normally drawn into an engine thru a vacuum line via a defective transmission modulator valve or some other defective part. Transmission fluid is very apparent and billows out so bad that you can't see anything behind you. Last but not least another type of smoke that is not white but black is the presents of to much gas/fuel being burned in the engine. If one of these fluids is low and/or you notice one of the symptoms that I pointed out above, then you know where to start looking for a fix.

I would also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

Is the heaps of white smoke come out of the tail pipe LONG AFTER the 15 minutes period?
To pin point a blowing headgasket you will need
1)coolant system compression tester
or
2)chemical reaction test for combustion test gas
If it's the org. engine from 1998,with over 120,000 then blown headgasket is a good possiblity.
Tow it to the shop and let the pro to do the coolant pressure test and combustion gas test.
A full head gasket job with head re-surface (if it can be re-use) is worth it.
Shop around on well estiblished independent shops.

My 2002 Opel Corsa 160i sport bakkie looses power when driving uphill but as soon as I reach the top it runs smoothly and gain power. Why does it looses power only when driving uphill?


It might have something to do with fluid like gas as it seems to act up when not level many drop the tank and clean out any sediment

Why do my car slow down going up hills.and go normal on straight roads


sounds to me it could be a plugged catalytic converter. the symptoms are runs good , no strain, or on the flats, then loses power with exertion, or long uphill to the point you think it's going to just quit on you. easy test is to unbolt the catalytic inlet, and give it a quick test run. sometimes you can tell by having someone race the engine while you monitor the exhaust to see if enough comes out of it. usually happens over 75,000 miles

HYUNDAI TERRACAN LOSING POWER... Hi, I have a 2002 Hyundai terracan that has been losing power. along the highway and straight roads it was fine but on an incline it loses power and now has a job to do...


run the fault codes for an exact diagnosis but from your description of the problem I would be looking at a failing cat converter as it may be blocking up the exhaust system

Ford laser 99 no power


Hi there.
well when you throttle up to about 2000rpm do you get blue smoke coming out the exhaust.When driving on flat road will it power up as normal with out missing or getting hot.
what colour was the old spark plugs were they black or light brown.
When you start engine and run for 3 minutes then let it idle and remove oil filler cap do you get smoke coming out.
Number 1 if yes then engine is lacking power due to piston rings worn answer rebuild engine.
Number2 spark plugs brown [good] if black soot as num1.
Number 3 if you get black smoke or blue ,then the engine is lacking compression could be your problem as num1
OTHER WISE GET YOUR TIMING CHECKED AND SET TO BOOK.

Check EGR Valve


To properly diagnose such situation you must supply more information. Such as: temperature: pressure fuel pressure tank level load area of operation which could mean driving uphill Downhill Flat Rd., Desert Road etc.

1998 Chevrolet C3500 dies randomly when driving down the road - uphill, downhill or flat surfaces. Typically doesn't happen when it's cold. Sometimes it starts back up and sometimes it doesn&#


my younger brothers' truck did the same thing and there was a relay up under the dashboard that would get hot and shut of(kind of a circuit breaker unit) most of the operating systems will flash at you when only battery voltage is available which explains the lights coming on..these newer trucks also have a performance chip in the system that will act up when it gets warm also..replace this and you may be ok..let me know what happens also.. good luck.

My 2000 montero sport has little or no power when driving up hill


First thing I'd do is replace the fuel filter. If the car runs fine on level ground or downhill but struggles uphill, it's usually because a clogged filter isn't allowing enough fuel through to satisfy the engine's demand for enough to keep you at speed going uphill. Try that out - it's an inexpensive part and is usually the cause of your symptoms.
