ever since i installed my A/F meter when im at a light, and i give it gas my reves up and then dips for a sec and then goes back up and, if i hold a steady RPM it will do that 3 or 4 times, then stay at the desired RPM. When then my rev is dipping my A/F meter goes from Rich to tottaly lean and then back (all the way across the spectrum) so whats the problem?

 

where did you tap the A:F guage?

 

there is nothing wrong, your meter only works at wot, and even then its crap. dont worry, lots of us have it and its a nice rave light show haha. just dont try to diagonist it or use it for any kind of real tuning as you will probally blow your engine

 

the o2 sensor wire under the hood

 

yeah but it sounds like crap when i give it gas and it goes up for a sec and then goes down and then back up

btw the rev dips by 100rpms

 

bump

 

I hear you should have tap the wire on the ECU...not the sensor.

when you unplug the O2 does the same thing happen?

 

unplug the O2? you crazy? and i tryed goin though the ECU and it didn't work right

 

bump

 

bump**

 

bump!*!

 

what they are trying to get you to see is if you change something and notice a problem the logical thing to do is to reverse the change and see if the prob is still present. unpluging the o2 snesor wire is not crazy as a quick test. are you sure the splics is not grounding somewhere

 

hmm ok

 

just a thought, does it do the same thing when the engine is under electrical load. Like the fan in high, ac on,ect? It kinda sounds more like the good ol vaccum leak.
