What gap on the copper heads? Going to change the sparkles soon.
Gap is the same regardless of plug construction. .052-.056 or something like that, but its printed on a label under the hood. FWIW, I always initially set the gap at the low end of the spec range because it is most likely to only get bigger over time.
Thank You for the info.
Thought that being Copper Heads they might be gapped differently from Platinum type plugs.
Once again THANKS
You're welcome. Do note that coppers generally don't last as long. Platinums can be good for 100K. With copper, I'd be checking them (condition and gap at 25-30K). Luckily pulling plugs on these cars is about as simple as it gets.
Engine stuttering at moderate revs while loaded is often a plug wire issue.
My Escorts like the Autolite APP5144 plat plugs.
I run those APP5144 double Platinums as well.
I tried the XP5144 iridiums once, the car hated them. I think they were in there for about 2 weeks if that. Had a slight miss and I went down a few mpg.
On the general issue of stuttering at moderate revs, the last time it happened to me it was the coil pack. But no need to go overboard. If plugs & wires are due, do them first. If tit doesn't help, coil packs (even Motorcraft) can be found for not much $$.
I will mention that I also have a '97 Ranger that was recently having serious problems under load (bucking/missing). Fuel filter and plugs done first. Fuel pressure tested within spec. New wires. New coil packs. (4 cylinder, but 2 plugs per cylinder, so there are 2 coil packs). Still bucking. Fuel pressure tested within spec again. Disabled EGR system. Bucking. Disabled evap purge system. Bucking. Fuel pressure tested within spec, including while driving with a rigged up extension for my pressure tester hose (gauge zip tied to a wiper while I drove). Started testing for consistent power to coil packs and etc. Found nothing.
Finally tested fuel VOLUME - it trickled with bubbles in it. What? Good fuel pressure with low fuel volume and signs of cavitation? Apparently it can happen. (And apparently I need a more responsive pressure gauge to catch the hiccups).
The OP's description points to ignition problem. But mine always did too. Just an FYI I guess.
It still fluctuates a little, but wtf? It's a 18 year old Ford thats probably worth a grand if I was lucky.
As long as it passes smog....
Did you do the plugs and plug wires at the same time, because Autolite plug wires aren't as good as Belden or OE wires.
I ran Motorcraft coppers in the SPI with zero issue but the Zetec likes the platinums so I run platinums in them.
Check the mass air flow sensor
