You guys are going to laugh at me but I swear this is true. Hell I should videotape it. I have an escort 8500 which i love to death. But since i have changed my plugs to the ngk-8's it does some crazy *****. Everytime I hit more than 8psi boost (as per my stock boost guage) it goes off full LASER until I let off the gas pedal. I got mad and exchanged the detector for another 8500. It worked fine for about 2 weeks and now it is doing the same thing. This one does it when I start my truck on occasion and when i nail the throttle. Sometimes it doesnt though.....I cant figure it out but its driving me insane. My brakes are going to wear out reeeeealy quick if this doesnt stop.

 

When you go over 8lbs of boost, your probably going so fast the poor radar detector can't keep up with the 10 cops you are zipping past..

 

Are those plugs non-resistor type or something?

 

Dont know.....Paul at REM wanted me to try them instead of tr6's. This never happened before I changed my plugs to the #8's

 

You might be onto something here

 

I posted a question about this last week. Are your plugs BR8EF or BP8EF? Our trucks have to have resistor plugs, the coil packs need them if I remember correctly, Sal at PSP told me this. I had a tuner sell me the BP7EFS, come to find out they will do damage in the long wrong.

The BR series plugs are resistor plugs where the BP series plugs are not.

You might want to check on this.

aren't those really cold plugs? what kind of boost/nitrous are you running with them?

 

no nitrous....4lbs over stock boost. I couldnt keep a set of tr6's in my truck. They always looked terrible...stock looked better than those things. These plugs im running now are NGK R5724-8 stock #7317

 

Detail, be SURE those plugs youre using have RESISTORS in them!!

 

I just looked them up. They are Non-Resistor.....Whats that mean and how bad is it????

 

Whats the exact model # of those plugs.

 

R5724-8


Look what I found...maybe solved the mystery..this is from NGK

Frequently Asked Questions
Q: When should I use a resistor spark plug?

A: NGK "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.

NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics.

They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.

In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion.

 

Dee, those arent resistor plugs.

Not only does running non resistor plugs make weird **** like you had been observing, they will ultimately blow out your coil packs as well.

 

Lovely......now I gotta change them again.....im soooo sick of changing the damn things.

 

You should be ok with a set of NGK BR7EF's
