Missing, stuttering past 4000rpm

[kelvinb]

i guess this is more for information then anything.

Missing

I got a 1g talon awd that was missing during idle. The guy i bought it from told me he just changed the plugs and that they were all good (as of 500 miles ago). well i checked them out and guess what? they were bosch platinums. number 4 was bad. The way i dertermined this was leaving the car idling and pulling individual spark plug wires out to see if it stayed the same or missed more. #4 was the only wire that held the same idle. the others made it miss more. Checked plugs, 4 was dead. New plugs installed, idles fine. yay!

Stuttering past 4000rpm

This took alittle more, but i just figured this one out. The only thing i needed was a multimeter with an Ohms setting, or resistance. the 0 thingy. Anyways i tested all the injectors, 2.6-2.6-2.6-4.8. (in spec is 2.5-3) injector was not working properly. So I believe that means the electricity rolling through line is not enough at higher rpms, causing it to miss. I will give you an update on this when i get a new injector. Hope this helps someone out there. peace

I would install a set of NGK BP6ES or NGK BPR6ES plugs and a set of wires.....my preference is MSD wires.

Those bosch plugs are junk

Did new injectors fix your stuttering problem?? How did you test them with the OHM meter and what should they read?

i would also like to know how you tested them

he tells his readings in his first post.
