My toyota innova manual transmission engine lacks power accelerating and its really hard to get 120km


Another cause of power loss in diesel engines is clogged fuel filter. Some vehicles have additional fuel filter INSIDE the fuel tank. I had my tank taken down and the inside filter cleaned and it fixed the problem. Some petrol stations and repair shops provide this service. If replacing the fuel filter in the engine compartment doesn't fix the problem, try this one. See FB "Toyota Innova Owners Phils" for more pictures.loss-engine-power-engine-still-running-ndjw3npn5oz5feiqbiqgnn35-5-0.jpgloss-engine-power-engine-still-running-ndjw3npn5oz5feiqbiqgnn35-5-2.jpgloss-engine-power-engine-still-running-ndjw3npn5oz5feiqbiqgnn35-5-5.jpgloss-engine-power-engine-still-running-ndjw3npn5oz5feiqbiqgnn35-5-9.jpg

Loss of power ,misfire, and strong smell of gas in 99 yukon 5.7


You'll need to pull the code from the computer to find what cylinder it is. It could be simple as replacing the spark plug (check it for damage) or the ignition coil. If the spark plug doesn't fix it, try moving the ignition coil to a different cylinder to see if the misfire follows that coil. If it does, replace the coil. If it does not, do a compression test as you may have dropped a valve or lost compression rings in that cylinder. Since there is raw fuel dumping into the exhaust there is the risk of fire from the catalytic converter.

I have a 1996 GMC Jimmy that was iddling very rough and code said cylinder 2 misfire check engine light was on solid. Replaced all plugs, wires, cap and fuel filter 1st of March 2013. It ran better for a...


Lets start at the beginning. Did anyone check fuel pressure before and after replacing the pump ?
Has anyone checked the fuel pressure regulator and the injector spider ? The 4.3w engine uses a spider with one injector that supplies all 6 cylinders. And it runs at 65psi or more.

Engine light flashing, strong sulphur smell, can feel engine missing as it runs. Assume bad plugs or wires?


If your engine light is flashing and sulphur smell engine power loss your probably looking at a catalytic converter.However you will need to have a engine scan completed to see what else is wrong as well.

There is white smoke coming out of the exhaust pipes. Car will not accelerate normally. Car sounds like it is missing. Need spark plugs and oil change.


Unfortunately you have a blown head gasket. The white smoke you are seeing is anifreeze burning.
If it was blue smoke it would be burning oil.
Gasket is in the top of the engine and must be replaced or you will ruin the rest of the motor.
Usually it's a $1800 repair with parts & labour.

Loss of power while driving. Thought it was a vapor lock. Had this once before and the car later started. This time engine turns over but will not stay running.


Hello,

Thanks for using FixYa.

The possible cause of loss of power is:

1. Low fuel pressure (Need to check the fuel filter and fuel pump. Fuel pressure needs to be above 45psi)

2. Dirty air filter (try replacing the air filter if its dirty)

3. Clogged fuel lines (use fuel line cleaner additive)

4. Bad ignition timing (use a timing gun to make sure your engine timing is correct)

These are the most common causes of loss of power for any combustion type engine.

I hope this helps you isolate the issue. Thanks and good day.
