Had to replace the plugs and ignition coils last summer and that fixed it.
As long as the Bosch ones match the factory specs then I’m sure they are fine as many other parts and sensors on these cars are made by Bosch.
My 2000 Ford Ranger with a 4-cylinder and manual is just about the simplest vehicle that could exist. SOHC engine, so not much that can go wrong in it. It's very satisfying to work on because you don't experience the shitty feeling of knowing you spent way longer on something than it should have taken.
Update: went Bosch for the plugs and ngk for the coils, the manufacturer plugs and coils were still in as if no one has touched them since the car was bought, I’m the third owner I believe. Each spark plug was toasted, easily double the recommended gap, and once I put the first two coils in (pulled code P0300, P0301,P0302) the problem entirely went away (coughing and sputtering exhaust, slow to accelerate, car shaking between 20-40 mph, rough starts) so I knew it was a go ahead for the rest of the coils. Feels like a whole new car all around, I can tell the engine is thanking me by what she’s putting out now ????
The best plug I found for a shovel is a Bosch Platinum WR8DP.
i bought ngk plugs and bosch platinum triple diode plugs and i got the coil pack off ebay.
I got misfires with FD5POR RS2 plugs. Almost 10000kms on Bosch f2cs this year. Been working perfect for me
Bosch spark plugs are junk.
This is why I don't use Bosch plugs. It goes back to the quad fire plugs with a platinum center electrode that would fall out.
Long story short: changed spark plugs 4000km ago as per my 2019 Hyundai Kona 1.6t manual. Followed Service manual, and the recommended torque on the side of the box of the Bosch (non OEM) replacement, 17 ftlbs.
Grounding electrode on plug #3 failed, destroying 2 valves and marking up the cylinder wall.
