so with my mini-me im having a wierd idle
at first it was really low so i played with the idle adjust screw to get it to a normal idle(600 compared to tach sitting at 0rpms) it sounds a lil better but it still fluctuates (and theres not a vacuum leak)
it also is a pretty rough idle
also sometimes if i rev it up it sounds like its gonna stall afterwards and sometimes does die

 

Any CEL on ?

 

i checked and i have cel 1
could the 02 senor be causing that?
if so that sucks i dont have $80 to buy a new one

 

Well an o2 sensor won't really cause a CEL to come on in a obd1 car. I guess it could but I'd check and see what the code # is first. Do you know how to check the code using the jumper wire?

 

seafoam helps with ruff idle.

 

i jumped it and it flashed once quikly
which is code 1 it has something to do with the 02 sensor...right?
i looked it up and its heated 02 sensor A

 

The code suggests the O2 sensor is bad. First, clear the code from the ECU to see whether or not the same code returns.

I don't think the O2 sensor is causing the idle problem. Try cleaning the IACV and FITV and also replace the PCV valve ($2-3).

 

^do what RonJ said

also, is there air in the cooling system?

 

I reset the ecu and it came back after a short drive i cleaned the iacv before i put the intake mani on so its not that I'll try the other suggestions soon

 

When you have the money to replace the O2 sensor, the CEL should turn OFF and the gas mileage and engine performance should improve.
