What type of air filter do you have?

If it's the "oiled" type (K&N), you need to clean your MAF...

If you are certain the Maf is free of oil residue...

I would look for a bad ground somewhere...

Good Luck...

crap I gota take my family some were, um does the ground
your talking about have something to do with the batt?

[Local Boy]

Bad grounds are a B*#tch to find...

Try checking across your Bat. terminals, with a volt meter, to see if you are getting between 12-13 volts...This will rule out a bad Bat.

Then do the same with the motor running...you should see @ 14 volts, with the Alt. charging...What does your volt gauge (in car) read, when car is on?

ALOHA

IF all check out "OK"...consider below...

When was the last time you cleaned/changed out the plugs? Maybe time for Seafoam treatment!!!

[sd8683]

Randy I thought our volt gauges were phony??

[Local Boy]

Nah...Not phoney...Just inaccurate...

I believe they read a little low...

mabey it has something to do with the pully system,
just a tought could be a altnator starting to go bad
I dunno its buging the crap out me I need to find out
this problem by this moreing its a must, mabey evan a
tighter belt, oh and I never changed those plugs ther
factory plugs I think?.
if im not mistaken I think the gauge in the car read, 12 - 14?
it floats when i rev?

A/C & defrost mode kicks the throttle up to keep the motor from stalling under the additional load of the compressor.
Might check the throttle position sensor it's on/near the throttle body.
Maybe someone can give the volts to see if it is within specs.
Do you have spell ^?

This is a classic.
Clean everything wash and oil your filter - put it all back together. runs like butta for a day then starts dozing off.
The fresh filter oil got on your clean MAF. Clean it again.
