Idle Jumping?

[zevirii]

Ok I know I seen it somewhere on this forum where you jump the "ten and grd" on the diag terminal and set the idle screw and the KLZE will stop jumping from 500 to 1500 rpms. My question is, since I can't find that post, Do you start it and jump it while it is running, or turn it off jump it and then start it?

Jump TEN and GRD then start it.

Going to try this tomorrow<P>Posted on <A HREF="http://www.probetalk.com" TARGET=_blank>www.probetalk.com</A> by Omaha95PGT<P><BR>The screw thing on top of the TB is just the idle adjust screw. The TPS is the "throttle position sensor" You have to loosen 2 screws on it and then rotate the whole sensor slightly. I'll take a picture of mine and put it up in the Pics and Vid section. Here's a link that explains the whole TPS adjustment thing.<BR> <A HREF="http://www.rs-productions.com/RSP_M...ech/tps/tps.htm" TARGET=_blank>http://www.rs-productions.com/RSP_M...e ... tps.htm</A> <P>If you do this you should be good to go.<P>Here's the accompanying picture in the Pic forum.<BR> <A HREF="http://www.probetalk.com/forums/sho...adid=1701006217" TARGET=_blank>http://www.probetalk.com/forums/sho...a ... 1006217</A>

My book says the samething.. I am not sure I want to mess with it, however I do need to get the idle correct so I can get the timing perfect.. I wanna make sure this thing runs to its full potential. Hows you car doing Ghandi?

Make sure your problem does not lie in the vacuum hose that goes from the brake booster to the intake manifold. The K8 an ZE use different length hoses and since I used a different hose, I did not realize that the original hose had a one way check valve in it and so for a few months, I had to set my idle at 1100 to keep it from jumping from 500 to 1500. Finally I got the idea to swap the original hose back and BAM! It idles perfectly. It was so Stupid of me to miss that! Oh well, it's fixed now. [img]shrug.gif"%20border="0[/img]

Check valve? Really? Where on the intake manifold did you plug the hose into if you used the same hose?

hey zev....my car needs a new head gasket mo $ mo $ mo $ hehe<P>other than that it kik *** when it was alive....yea the shop set my idle to around 1500-2000...i was like thats damn high...but when i got it to idle around 1000 everytime i came to a stop and pressed the brake the idle would jump around....oh yea i messed with the tps before i saw that it said not to in my chiltons....haha<P>anyways...i will hopefully have a shop replace the gaskets for me...the cheapest i have found was $300 for labor...but i am lazy and have only called 2 garages....would be a diff story if i didnt have another car...<P>AJ

Damn man that really sucks... Was it the overheating that caused it? Get it fixed fast bro.. We are trying to have our meet Nov 17th

[ghandi1981]

damn i will be in san antonio on the 22-24...sorry i cannot come up the the money to fix it that quick....no what was causing it to overheat was a fuked up radiator cap....replaced it....THEN a couple of days later i noticed that the freaking radiator hose had a tear in it when i got to school (45miles from my home)...when i got home i had to goto work so i stopped by o'riley and auto zone to get the hose....but both had to order it...so instead i bought some sort of tape to wrap around the hose that keeps up to like 100 psi....on my way to work the temp started to rise...i turned on the heater and the temp went back to normal....then it went up again so i dropped my car off at a buddys hose a couple of blocks from work and was going to put the tape on the hose after everything cooled down....well i got back a couple of hours later and wrapped the hose in that stuff and let it set for like an hour....then i drove home....stupid me for drinking(friend had a lil halloween party) that i forgot to put water in the system(although there was some still in the reservior)...DUH!!!!... so on my way home i noticed that the temp gauge hadnt moved a bit...NONE....so i put on the heater and NO heat was comming out...i thought that was strange...well i let my car sit over the weekend and got the hose in and replaced it....but then i noticed there was was looked like oil in the coolant system and white smoke was coming out of the exhaust...so i figured that i blew it....but i still need to run a compression and leak down test...<BR>AJ

put the old brake line on with the check valve in it.. I didn't fix the problem. I double checked all vaccume lines, so I guess I will have to adjust the TPS now... Any other Ideas?

[zevirii]

I adjusted the TPS and sure enough that fixed the problem.. Idles fine now..hmmm so easy...hehe
