The knock is because the EGR not opening or its passages in the intake manifold are plugged. And the Knock is causing the KNOCK SENSOR to ****** the timing to reduce detonation Test the egr by hooking up a vacuum pump to the egr and while idling pump vacuum the engine should stumble and nearly die until you release the vacuum. If it does not or the EGR will not hold vacuum first if it will not hold vacuum replace the EGR then test like I described a bit earlier, If the engine does not stumble at all you need to clean the EGR passages and sometimes this means removing the intake plenm and cleaning that way whic is actually the best and only way to completely remove all the carbon and while you are there replace the PFE SENSOR Or sometimes known as the BACKPRESSURE SENSOR If you need parts only BUY ORIGINAL EQUIPMENT FORD PARTS BECAUSE FORD HAS SO MANY UPDATES THAT ONLY FORD HAS THE MOST CURRENT PARTS !!!!!!!
If this information helps and it will prove to be correct I have done this hundreds of times while I owned my diagnostic shop for 14 years here in Seattle,
Please give me a fixya Rating Thanks and if you need further help please contact me Thank you, Randy

Ranger looses power up hill

I am assuming you have the 2.3 liter 4cylinder engine.. This is common in all rangers straight out of the factory with that motor. Your asking alot out of a 4 cylinder truck that also get good gas mileage. they just do not have the capacity to gain speed up a hill. There are a few solutions for you that you could try. If it is a 5 speed manual transmission try to speed up before the hill and when you start losing speed go to 4th gear. this is also good for using as a passing gear as im sure you have noticed you lack power when trying to rapidly accelerate at highway speed to pass. an aftermarket cold air intake combined with a less restrictive exuast will give you anywhere from 5-20 hp gain AND give you more MPG's

Or you can buy a light truck with a v6 or v8 in it. rangers can be equipped with v6 as can chevy s10's. dodge dakotas have the availability of small block v8. this is of course will cost you alot in gas (based on experience) I am a 10 yr mechanic and have owned 2- 4 cylinder rangers a 93 and a 94 my dakota which i still own is a 01

1999 Volkswagen Jetta will not shift good

Volkswagens are known for having trouble with their transmissions, even more so in the 1st couple generations. This problem could just be your transmission sticking when getting into another gear. I recommend not pushing the car so your running at high RPMs, slowly work your way up that hill, and even try letting off the gas it may help it shift some. If you're really concerned with it you can take it somewhere to get the transmission checked, something maybe slipping or sticking it all depends and it can be a small inexpensive fix or it could be a heck of a lot, but its all up to you.
