Share a simple DIY that resulted in your engine running smoother, more efficient?

billabong02 · 06-18-2020, 06:43 AM

I'm gonna be cleaning my MAF sensor and swapping out the old air filter. I've read that cleaning your MAF sensor can improve things like throttle response and potentially regain some lost mpg.

Are there any other simple DIYs apart from a full service of course that you noticed brought some sort of improvement in your engine's performance or overall efficiency, etc?

Things that maybe get overlooked?

Spark plugs....coils.....

If you have access to coding, clearing all adaptions always makes the engine run smoother...if only for a while.

New coils have a similar effect, though I tend to be an 'if it ain't broke' person when it comes to coils...

Coils as in ignition coils?

My end results were both! Not to mention it made me 3 inches longer and 2 inches fuller in girth.

That's a pretty good one to clean out the carbon in the system.

If you have a direct injection motor....fuel additive isn't going to clean carbon off the valves....
