curious...
:confused: i have an 87 GXl 13B all stock except for an intake. when i first start it, it does its normal 3000 rpm rev then drops down to about 1750. then i bounces from there down to 1400 and back until the engine warms and the idles gets below 1500. is it supposed to do this? if not, what can i do that will fix it?

sounds normal... atleast i hope so cuz mine does something similar... 3k for a few seconds... drops then around 1500 ish .. normal to me
|
mine does the same starts at 3g then drop to 1500 until u either blip the gas or start driving then it drops to normal idle speed
|
Surging is not normal an indicates a bad or mis-adjusted TPS.
However cold start in neutral should first rev to 3000 rpm then idle down to around 1200, and as the engine warms then down to 650/700 rpm |
Mine does the usual warm up but then at a certain point it revs up and down from like 1500rpms to 2000rpms but only for a minute or two then goes away and she warms up just fine

Well it only does this on the warm up and no other time. And I looked closer tonight and it's only going from 1250-1500. I'm not bothered by it at the moment. Car runs great and have no issues with it driving
