What's the logic behind clogged fuel injectors decreasing fuel economy? Shouldn't it save fuel instead, since less fuel is being injected to the engine because of the clog?

I have an 07 Avalon and it recently started to have an issue where, if I floor it, it will take move then have a brief 2-3 seconds of lack of power then take off. The oil currently used is the semi synthetic grade. Not sure why this started to happen. I plan to get the spark plugs changed soon even though it may not yet be needed but it is a costly job being that I don't have the tools needed to do this myself.

I have a 93 crown Victoria and I get average 13.9 mpg I get white smoke out of my exhaust sometimes, and I feel a slight loss of power. When I step on the gas a lot my check engine light comes on for a few seconds then turns off.

My Mazda 3 2015 has had some of these symptoms for the last year. Low mileage, bouncing idle when in drive and at a red light or something, misfiring when I start it usually takes 2 to 3 attempts. Also check engine light on and off. My mechanic said code was related to mass air sensor. He replaced the sensor but didn't help with any symptoms. Got a new battery, so that's not the problem. Mechanics here in NY are very lazy. I'm at a loss what to do.

my car runs fine at high speeds but at low speeds seems to missfire not sure what the issue may be and when idling the idle is rough and sounds a bit cammed

[yvonneshealey]

My problem is at startup. It acts like it's not getting the fuel it needs at start-up and white smoke is coming out the tailpipe. I've used injector cleaner and it took care of it till now. I'll use that again till I save to get a complete injector cleaning.

Hello, can you tell me if I replace all bad diesel injectors with new, in my engine (Ford Focus 1.6 tdci), will it already improve obvious weak power I feel every day, or does't- perhaps if turbine pump is also demaged (during driving with bad injectors maybe). Does setting new injectors with old pump is good solution with no worries in future? Thanks

[mrkevin]

Question my Uncle who is a mechanic told me my fuel injector has a leak, inside the car it smells of diesel, under the hood it sounds like a ticking noise also smoke under the hood and a lot of smoke coming from the exhaust.

Are these symptoms not showing something worse? No check engine showing

I'm hoping this is what all is going wrong with my 08 Chrysler Town & Country. The engine completely stopped one night, and while it turns over, it only runs for a second or two. Things I noticed leading up to that, pinging (thought it was knocking), the aforementioned rough idle and severe mileage loss. The first few times I got it started back up (before it shut off again) it backfired multiple times and sounded like a lawnmower before it shut back off. I feel like it's definitely fuel related since I had another car sound like that once, when the fuel pump went out. Is the lawnmower sound common with bad fuel injectors?

Bg44 k platinum excellent product for cleaning carbon deposits u will notice the difference

[jcoach]

Now plz make a step by step video on replacing it on a 02’ bmw e39 540i

2013 chevy Silverado 1500 5.3, struggles to start every morning. Sounds like it kills then suddenly starts at a high idle. Once the engine is warm I have no trouble starting it the rest of the day unless it sits about 8-12 hours without being started . I use marvel mystery oil in my regular fuel ups and sea foam In fuel at oil changes

[norman]

Which is the BEST fuel injector cleaner ?

[jetknight]

Not going to waste my time cleaning or replacing the O rings
I ordered all six brand new one's
And not deal with another one going bad... did that before and now the problem came back. .

[Akeldama]

Just bought a 2013 Mazda cx5 and the oil smells like fuel but only once did it have rough idle at start up and only rough when in park and reving it but when driving it feels fine.. would this be a bad fuel injectors? .. I also have a check engine light for o2 sensor or manifold I think that’s what it was or it’s my exhaust leak that has 4 little holes ..

[davidbaros]

Would the ck engine light not be on with bad injectors, as well?
