I installed a Zex kit today when finished the check engine light came on I am using the resistor wire included in the kit Anybody have any idea's what causing the CEL to be on?

 

Theres a procedure with key that will read out the code on the dash board through blinking the light or go to autozone and get it read.

 

had the computer reset and now it's fine

 

Do you know what code was pulled? If they just cleared it and there is a problem the light will come back. Make sure you know why it came on or what code they pulled at least.

The code said high air temp circuit I guess It was the mass air flow.I really think when I taped into the tps it noticed a change because everything was fine till I spliced into that wire. I have a 55 shot right now till I get new plugs and utec. Have sprayed it about 4 times & it works great. Motor sounded clean and felt good. Does any know a part # for the NGK colder plugs i need. So I don't confuse the guy at the auto store?

 

The 1-step colder NGK Copper core number is LFR6A-11 (Stock# 3672)

 

dude... here's the deal you really dont need utec depending on what shot you use. I've been running a 75 all day for the last 6 months w/o utec. Now i've been told that a 100 shot wouldn't need an EMS also; and this was told to me by someone thats been doing this race thing since the 70's...
he says "if you motor starts to knock the ecu will pick up on it and take out timing."

 

I would rather be safe than sorry don't want a hole in my block if you know what I mean.

 

then you would already have colder plugs before you even sprayed

 

Its just a 55 shot smart ***

 

a 55 shot wouldn't even break a lawn mower!

 

So basicaly get the code read and get that fixed up then get some 1 step colder plugs. Its anther 70 bucks or so but really the best way to protect your engine.
