Re: Idle/tune-up/vacuum/oil BING!!

You asked for a lot of information. Here are some asnwers for you.
Check the linkage at the gas pedal, if bent it prevents you from 
opening the throttle plates all the way (or maybe the carpet or floor 
mat is in the way). The micro you hit at WOT (Wide Open Throtle) tells 
the lambda to run "flat out". The extra plug by the Lambda micro is 
for the kick-down switch for the automatic transmission (omitted for 
the 5-speed). DON'T TOUCH THE IDLE SCREW THAT TOUCHES THE IDLE MICRO! 
Unless someone f-cked with it, LEAVE IT ALONE! Just make sure that at 
idle it trips the micro without beating it up. It is not an idle speed 
it only tells the idle system to run. You CAN replace the distributer 
cap, rotor, and ignition wires without disassembling the motor but it 
is much easier if you remove the fuel mixture unit and intake 
manifold. As long as you are digging in that deep you should replace 
all the seals and hoses and water pump. Rob Grady will tell you you 
need his Water Pump Master Kit. If all your parts are origional you 
really do need it. You should also replace all the hoses and belts and 
idler bearings too. The best way to find vacuum leaks is to disconnect 
the vacuum lines and see if the motor runs better unless you have a 
vacuum tester so you can test things individually. A hissing mode 
switch is a vacuum leak. Just snug up all three brass screws and leave 
them alone. The idle mixture screw is INSIDE the unit under a 
tamperproof plug (if it is still there). At the least make sure there 
is a plug in it. It is just to the rear of the air intake and air 
sensor plate. DON'T START TURNING IT WITHOUT AN EXHAUST GAS ANALYZER. 
Chances are (if it wasn't f-cked with) it is close enough to pass 
inspection if everything else is OK.
Pull the front left wheel and see if the shock is still there and if 
anything is hitting it, it might have come loose or bent and is 
hitting something.

a tinyelectronic piece BUT i know what the problem is. I also adjusted 
the throttle linkage. A problem i noted while the throttle cover was 
off.. when the gas is depressed all the way the thrttle still didn't 
twist all the way. After adjusting the best I can manage is JUST 
before actuating the full-throttle switch.. otherwise I bring the idle 
back up. Is there supposed to be something plugged into the plug next 
to where the idle spd micro plugs in (plug plug plug). I'm doing a 
tune up sometime this week. I asked Rob Grady, and as always he was 
very helpful.. BUT in this case not enough so. Damn that 
distributor... HELP! Any tips... ideas on getting that con-sarn thing 
out of it's little nook at the very back of the engine? it is safe to 
remove the fuel distributor w/o messing up some fine adjustment and 
w/o having gas all over the engine? Always, what's the best way to 
start finding any vacuum leaks..

start? It seems to idle ok with the microswitch hard-wired, so i doubt 
vacuum problems... but i'd like to give her a once-over anyways. I 
went to snug the bass bolt on the intake closest to the rear of the 
veh, an with literaly no torque i broke the head off... think it's 
safe still?

the fuel distributor and the intake right? I can't see it!!! Picture 
anyone? Oil, Coolant, fuel, wiper fluid... what other fluids are 
there.. (manual tranny).. trying to identify this greenish oily stuff. 
doesn't seems like oil or antifreeze or a mixture thereof... 
road-nasty?? Every time i hit a bump there is a "bing" (like a service 
bell) from the passenger front wheel? Any ideas? A little gremlin 
hitting the spring with a ballpeen hammer was my guess... but he must 
keep hiding. Michigan roads suck! ahhhh... HELP!! thank you thank you 
thank you THANK YOU!! i don't know how some of you guy(and girls) find 
time to answer all of the less-experienced people's questions... but I 
think I speak for all the DeLorean novices when i say THANKS!!!!!!!!!!
