Okay.. my truck has been doing this a while now.. but SOMETIMES when i get on it.. and hit 4500rpm or so (sometimes 5) my truck misses? or acts like the rev limiter is right there.. I just replaced plugs.. and fuel filter. I'm thinking its coil pack or MAF.
Has anyone else had this issue.. here is a video.
listen to 1st gear.. and again in 3rd.

 

Try replacing plug wires. What brand of plug did you use?

 

i can promise you its not the plugs man. I'm thinking its the coil pack.

 

If you have never changed the plug wires, change them!! Has it thrown a CEL?

 

Nope.. no check engine.
truck has 66K on it.. i just replaced the spark plugs with bosch platinums... people have said it to be the coil pack.


we even pulled codes from the computer.. lol. my stepdad asked me if i had hit the governer. haha.

 

Big mistake on the Bosch plugs!!! You should have used Motorcraft double platinums, or fine-wire platinums. Replace the plug wires, and put in a set of Motorcraft plugs, and it will be fine!!

 

You sure its not the coil pack man?

 

I just put bosch platinums in mine..why big mistake?

 

Yes!!!

Bosch plugs do not run well at all with Ford's EDIS!!!

Check out these threads, and then decide about Bosch plugs:

i see. well maybe when i get some more money i can spend i'll get some different ones. and i changed my wires today.. and the damn thing is still doing it. so i'm guessing Coil pack now?

 

I tried Bosch in my 03.Motorcraft plugs went in it 2 days later.

 

yeah, domestic vehicles just don't seem to do to well with bosch. I couldn't get motorcraft plugs around here so I went with autolites and they worked great for me.

 

autolites or motorcraft.

Get some new plugs and your truck should run good as new. I don't think your coil pack is the problem.
