jlyon Posted July 3, 2013 Report Share Posted July 3, 2013 i changed the plugs and used pulstar plugs. my edge had 112,000 miles on it, so it was time for a tune up. change them out and had a coil go south on me. got that fixed and then had a "bucking" problem when under a load, like when going up an incline. it felt like it was having a misfire problem, but i had no lights coming on at all. thought it was the VSS and/or TSS, so i got them and replaced them. still had the same problem, but the trans shfited alot better. looking at the sensors, they needed to be replaced anyway. yesterday, i pulled the pulstar plugs and put in Autolite XP iridium plugs and did a carbon clean on it. drove it home last night and it was perfectly smooth all the way home. my edge either didn't like the pulstar plugs or one of them was bad. i bought them online from Advance Auto parts, sat on them for about 3 months, and now i can't send them back. live and learn, but $65+ is not a cheap lesson in my world.

fordtrucks71 Posted October 22, 2013 Report Share Posted October 22, 2013 Pulstar spark plugs are a gimmick. Much better off with Autolite XPs or even Motorcraft! Quote Link to comment Share on other sites More sharing options...
Edgieguy Posted October 25, 2013 Report Share Posted October 25, 2013 Your results are the norm for these plugs. Read reviews on them and you will see that many others claim that the plugs ruined other parts and that the car never drove correctly while they were installed.
