ok, this is for the SC'd guys.

wondering if anyone has had, or is having the same issues as me.
#1 power surging.

This has been going on for awhile now..at idle, the car will seem to have little or big "power surges" where the idle will run smooth, then when the aux fan kicks in, the idle suddenly dips ( sometimes almost stals) then kicks back up. and it would do this every 30 seconds, however if i did not use my climate control..its fine..
then my battery died..well to the point, i had to jump start it every time i turned off the car..

so i get a new battery and eevrything is good..except..when i try to run the climate control, same thing, idle dips low and seems as if the car is struggling to idle..like it had some huge cams..

now im begginning to wonder.. is the little smaller battery too small for our cars? like doesnt haev enough capacity to properly operate the car??
so next week, im gonna get a "full-sized" battery again and re-locate to the trunk. cuz as we know, there is NO room for a bigger batter under the hood for us SC'd guys..

and #2

do any of you guys have a PCV valve? cuz i apparently am missing one..or is it supposed to be this way. I know its supposted to be located on the line from the rear valve cover to the intake. but i dotn have one..just a tube connecting the 2..and i cant remember if the SC is supposed to have one or not..

cuz i have ALOT of blow-by oil getting through and leaking out of the intake cone..so im thinking of installing an in-line PCV valve on that tube, or getting a catch can..

then again, i also "may" have blown a land ring..but im not 100% on that yet..


sorry for the long post...but any help would be great../

thanks

 

Check your air conditioning. I've had 2 Ford Escorts come in with poor idling concerns. It only happened with the AC on, so I checked the refrigerant, and nothing came out. It had 85 PSI, but I recovered 2 oz of refrigerant. I refilled it and checked for leaks. Nothing, so I sent them on their way. It's been good for 4-5 months. No comeback, no calls, no concerns. The A/C works perfectly fine. It's a friend's mother-in-law and another friend.

 

AC and stuff all works fine...

just noticed another thing...
lets say ur at an intersection or ur in traffic and just creeping along..and stop..and go and stop...and such..
well if im just giving the throttle little peps..to move ahead..when i give it a few peps, then let off the throttle, the rpm, drops below 500, then back up to a grand..then back below 500, then back to a grand..then back to normal..
and on occasion..it does this, but will almost stall...

and now..i just put in a new battery..i drive it home...park and leave it running for a few mins.cuz i wanna see what it's gonna do..
the aux fan kicks in..and idle gets all messed again..like goes dwn and up and down..even after the fan has turned of, the idle still goes upand down a few more times...almost stalling..hmmmmm

now im thinkin..could it be fuel pump...or not enough fuel pressure getting through

 

ohh.,..guess i should also mention i have a cylinder 4 misfire code...
ive heard of others having miss fireing issues too, and the car stalls or shuts off..
mine has done that a few times too...
so is all of these just a symptom from the miss fire?

 

Rough idle sounds like a vacuum leak.

 

ohh....youre missing a pcv valve? Doesn't sound good. Don't know about this SC setup but I think you need a PCV valve.

 

You might wanna post this in performance and modifications... I think of those experienced SC guys read more threads in there than in here and you're likely to get a very detailed answer.

 

hmmm how do i move the thread?
