Hey guys so i just put in a set of +4 boush plugs and 9mm jba wires. It starts and runs fine. But when i hit the gas it sounds off. kind of hard to describe. Also my lights are allot brighter. I am not just talking about the interior lights i mean everything seems brighter. whats up with that. am i going to burn something out or melt a piston. I am driving to Ontario tomorrow afternoon so i don't want to get stuck on the side of the road in the middle of no were. any input would be much appreciated.

Bosch plugs are known for their bad quality sometimes. I run a set and have no problems.

Did you make sure installed the wires in the correct order?

 

Yes i am sure i put them in, in the right order. I did one at a time.

 

What noise is it making?

 

rough. Like i needs a tune up or it is missing.

 

Go over the plug wires and plugs again. You could have a bag plug, wire or both. Also make sure the wires are firmly pressed onto the plug and coil. You should here a slight click.

 

Did you check the plug gap before installing them? Most plugs will come pre-gapped, but it is generally a good rule to give them a check, you never know.

 

And i put in a red top as well. If that makes a difference.

 

You were probably just used to a weak battery and the red top fixed that.

I mixed up 2 wires when I changed mine. Ports five and six are actually six and five or something like that on the pack.

 

witch ones are five and six because if i did mix one up it would be on the passengers side.

 

to my understanding, there is no gap to set on the bosch +4s. i've never ran them, but this is my understanding of the matter.

 

I did the same thing

 

Correct. You can't set the gas since there is no room.

 

Ahh I see, I use ngk's seem to have worked well for me

 

Bah another one falls for the +4 crap...

 

x2

i dont know why people with passenger vehicles and light duty trucks think they need those.

thats probably the reason it sounds like ***, you have over-priced crap spark plugs in it

 

LOL... unshrouded spark kernals are basic science. Which seems to escape most.

btw, you can do the same thing by having a plug with a reduced ground strap and indexing them. But hey.. what do I know?

Good question.....but running plugs too cold, and too short, aren't good things to do!!

 

I fixed the problem. It was just two crossed wires. It runs like a top now

 

So... you didn't change them one at a time... by the way, does it run better with the new wres? Always wondered about the JBAs.

 

Takeda to the OEM rescue........ Wait there's no picture yet... I am ashamed of you Bob.....no testing data from a 1000 source's....

 

It runs great.

 

****** those pos bosch plugs out of that thing and put somehting else in it.......those +4 plugs are crap. i worked at firestone in austin and thats all we put in and every other car would come back saying that the car ran like crap

 

I have no problems with them

 

so what plugs do you all use then?
