i changed my spark plugs to bpr7es and my car ran fine for a couple min then it felt like it was running on 3 cylinders. I pulled the plugs and they looked burnt. So i went and got bpr8es then i got the same problem whats going on. It just runs realy rough and idle drops to like 500 rpm and almost dies. Feels like its runnign on 3 cylenders whats going on thanks.

now pics on page 3

 

Try to do a compression test and/or leak down test. Also look into replacing the coil pack if you pass both test.

 

any other ideas i need this car to run its my dd

 

I recently had the same thing happen. The only way I could tell was that my EBC kept shutting down and powering back on and the selonoid was going nutz. I took the plugs out chacked them put them back in, same thing. Started ripping my interior apart to get to the EBC wiring. It all checked out. Finally put the old plugs back in and everything was fine again. I have no clue what did this, and I am still running the old plugs and till I have time to really figure it out. The only thing I can figure so far is that one of the plugs was a brass color on the nut the rest were the silver I am used to seeing but they all checked out as BPR8ES's as per the writing on the plugs??????

 

anyone explain whats going on i need to get to work tomarrow ill try the original plugs later to see if it corrects the problem.

 

First Make Sure That All Coil Pack Are Plugged In All The Way And Have Clicked...

 

What gap did you set them to?

 

0.26, if i am remembering correctly. I have all that info on a spec sheet at the house.

 

I had a similar experience using coppers so I ended up getting iridium plugs and they worked great. I never found the reason why they didn't work for me but the iridiums haven't given me any problems.

 

make sure you plugged the clips in till it clicks...i forgot to clip one and it sounds exactly like what you are describing

 

...it's probally because, when u replaced ur spark plugs they didn't "click" to the wire's from ur coil's.... cause the stock NGK one's r thinner then the NGK that ur probally want to use...that was the case with my's..they we're "thicker" so I needed to make sure that they all clicked...which u need to use some "muscle " I changed my's at 8k "11k now" and they have always worked great ... I bought my's at Pepboys so if helps...

 

Any new results yet. Did you figure out the problem due to the the plugs material or whas it not clicking?

 

ill let you know im gunna do it right now. First i will check to see if it clicked if that deosnt work ill try iridiums.

 

i put the original plugs back in and it idled fine for about a min then it started doing it again. What should i try now?

 

what do you guys mean by clip's. the boots to the plug?
