glh-t runnig funny

[grim]

last weekend i started the glh t . i did the t2 conv to it . it ran ok when i first started it . i hooked the a/f and boost gauge up today and changed out the stock t2 tona lm out for a stage 2 lm . it starts easy but it idles at 1000 and jumps up to 2000 then back to 1000 again . it did this before i changed out the lm so its not that . i unhooked the temp sensor and timed it to 12 .all that looks good . the a/f gauge is hooked to the only black wire on the blue connector like on garys site . well it jumps back and forth with the rpms , going from lean to full rich .
thanks in advance

Try Changing the AIS motor.....and the guage is suppose to jump from lean to rich at idle...

im not sure if your car was set up for A/C or not but one of my cars when i took off the belt for the A/C and then turned the a/c on it would do exactly what your describing but I think the ais would be a better guess right now.
