andrewwynn, now you indirectly implying I am dumb, foolish. a dumbass and moron. For someone that is touting a 150+ IQ you must not have been there the day they taught how to win friends and influence people or when to leave well enough alone. Please recall that I said to you it was not necessary the first time and certainly not the second and now the 3rd time is just plain ridiculous. You don't realize that saying-- based on the follow up questions it appears-- means you assume based on the follow up questions the fuel pressure wasn't tested.

FYI-there are no circumstances that I would see as appropriate to call my brother a dumbass. And, Upallnight and I are completely capable of managing our relationship. We don't need a backseat driver.

Bc you read entirely into that wrong 100%. You for some reason I can't fathom take offense at a very common phrase that I've used since I was about 8 and l learned it from Felix Unger on the odd couple. It's my contention that you really have no reason to have thought that was overly un-nice.

I was offended by you taking offense and making my own stand not related to other people. I re-used the phrase on purpose to make a point it it not a derogatory phrase it's merely the expected phrase for the exact circumstance.

What I *implied* was actually nothing at all. What I literally said was that we are ALL guilty of being moronic but only specifically applying that to myself (and my brothers who on occasion as myself deserved the moniker). Example : brother thought it would be funny to touch my neck with a donut just pulled out of hot oil. That is "being a dumbass" and he deserved to be called out on it. Having 7 younger brothers and about to turn 50; there were countless examples when each of my brothers and myself have earned the title.

You I don't know well enough and it would be moronic on MY part to attempt such a misjudgment (to call you dumb or even imply it). I only sense there was some misunderstanding and also that for as I said some reason I can't fathom thought that phrase was meant to be more disparaging than literal.

I did say that maybe you goofed and sent us down a rabbit hole implying that one key test was performed that possibly wasn't and should be verified before going on. Dumb? No not at all. Goof? Oversight ? Sure. I make mine daily nobody's perfect.

That makes 4 times. I suggest you let this go and move on.

The reason you can't fathom my point of view is you aren't acknowledging another frame of reference or interpretation other than your own as having merit.

I didn't drive the car for a couple weeks- and now it runs beautifully! No errors (ODB) it accelerates back to normal.

I really hope that's the end of the issue, but would love to know what could have happened here.

To refresh, after replacing the MAF, the accelerator would only work up to say 20% of the peddle- then it would putter. I big guess was that not enough fuel was being injected. Car had sat for several months un-driven.... Then I drove about 10km and it had the accereration issue. I left it another 2 weeks, and now she runs fine.

Is it possible the fuel needed time to "settle" or something?

No definitely not a "settle" situation however a bad connection or a problematic commutator. You could have had some clogged injectors from all the odd starts and long pauses between driving. I would be prepared for the issue to return but as long as it doesn't it would be impossible to diagnose anyhow. Hope it was just some dirty injectors or bad gas. I would run some fuel system cleaner and get some full tanks of 93 through the engine. Great news though

Oh the pleasure of finally opening up that engine :)

I'll grab some fuel system cleaner. I normally fill up with 95 or 98 petrol. Is that ok?

Also, the FOB remote has stopped working (so I can't remotely unlock). Worked a few weeks ago when I last drove.

Should a bit of driving be enough to charge it?

The remote fob probably deprogrammed with the battery on the car going flat or disconnected. You'll need to reprogram it.

The key recharges any time the key is in the ignition and engine on. It takes a while like hours to fully charge if dead but the charge lasts a long time it's not likely the fob battery is dead. Do you have two keys?

Fuel octane rating is clearly different in your country. Use the highest available at normal stations and use only top tier gas for a few tanks.

So nice to hear the engine is running properly.

I've got another key, but it's just the grey one without buttons (see photo below). It unlocks doors and can start the engine.

Deprogramming feels a bit unlikely, as the remote was working fine last week and I've removed/changed the battery several times before.

Unless this is all related to some mysterious electrical problem that even affects the key!?

Just drive around and see if the X can recharge the battery in the FOB. Do you have another key? If not, this would be a great time to get a spare key with a working fob so that you won't be posting later, how to get into my lock X since the key tumbler is spinning and the FOB is not working to unlock the X.

Don't be like this Guy.

Both of my keys suffered a broken solder joint. I reflowed the solder and brought the back to life. I lost one of my keys (ouch) and the remaining one apparently the solder joint broke again.

I'd suspect the same with yours. It's nearly impossible for the problem to be that the fob battery isn't charging.

If I had my valet key I would cut the fob key open and reflow the solder joints. You don't have the ability there is a guy that does x5 key refurbishing for $60
