I Have A 88 Gxl And I Am Having Some Trouble Getting Her Back On The Road . When I Start Up My Idle Fluctuates Up And Down And When It Reaches Warm ,It Usually DIES Die. My Cas Was Replaced And I Am Not Sure If It Was Timed Correctly . when I Try To Drive I Have Almost No Power Kinda Like I Am Trying To Start Off In 2nd Or 3rd Gear When It Does Get Going It At Times Feels Like It Is Gonna Cutout . I Just Don't Know What Or Where To Start With Fixing This So If Anyone Out There Can Offer Some Detailed Info And Please Keep In Mind That I Am Fixing By Myself And It Would Be Helpful If At All Possible I Could Be Walked Through The Steps To Make Sure I Understand I Would Really Appreciate It . Do You Think Maybe I Need A New Tps? Can I Somehow Check The Condition Of It ? Would My Car Still Run If This Part Was Bad? PLEASE HELP ME UNDERSTAND SO I CAN HAVE MY CAR BACK ON THE ROAD BEFORE SUMMER IS HERE!!!

 

i dont think it is the TPS. But unplug your TPS and then try running your car. Should run fine with the TPS unplugged.

 

maybe this site could be of some assistance. GL

SO WHAT DO U MEAN ? IF I UNPLUG MY TPS IT WILL MAKE NO DIFFERENCE IN HOW MY CAR RUNS? AND FORE THERE IT SHOULDN'T BE MY TPS CAUSE THIS HAS NO AFFECT ON HOW MY CAR PERFORMS POWER WISE?

 

here i made it easier for you.

well the TPS does effect the car and how it runs. But if this were the problem you can simply unplug it then go drive your car and see if you have any problems then. That is how i figured out wether or not my TPS was bad or not. It was s imple connection issue with mine. I just cleaned it up and plugged it back in. Simple as that, but it was causing the power to cut at 6-7k rpm.

 

THANK YOU I DID CHECK OUT THE SITE AND IT WAS HELPFUL IN ALOT OF WAYS OH AND THANKS FOR STICKING UP FOR US GIRLS OUT HERE WHO DO ACTUALLY KNOW A THING OR TO ABOUT CARS WHICH I AM SURE IS ALOT MORE COMMON THESE DAYS SINCE IT ISN'T LIKE THE OLD DAYS WHEN YOUR OTHER HALF ACTUALLY DID GIVE A FU@# AND WOULD FIX YOUR CAR HIMSELF . I HAVE COME TO LEARN THAT THEY THINK THAT IF IT ISN'T RUNNIN THEN NEITHER AM I BUT I THINK THATS WHERE HE'S WRONG CAUSE THE LONGER I SPEND TIME LOOKING AT MY CAR AND WISHING I COULD BE DRIVING IT THE FASTER MAYBE ONE DAY I WILL BE ABLE TO HAVE IT UP AND RUNNING BEFORE HE COMES HOME NEXT TIME AND THEN WE'LL ALL SEE WHO'S SITTIN AROUN WAITING FOR WHO TO FIX SOMETHING FOR THEM! HA HA!!

 

Turn your caps lock off please. Thats what im trying to say

 

just a reminder, dont go off topic or start any drama in the threads. it will just lead to getting your thread locked and you wont find the answers your looking for. Lets stay on topic please

 

I'll keep comments to myself.

So did you fix your car?

 

Um.......when was the last time the car got a tune-up. Fuel filter could be clogged, could be all kinds of things. Do a FULL TUNE_UP(spark plugs, wires, fuel filter, ect.) then see if it still doest it

 

Add me to aol at: RX7Jager or MSN at engel_flammen@hotmail.com, I'll answer yo ****.

 

Back on topic:

Check your idle speed. If your idle is set way low than it could be bouncing because the BAC is trying to raise it unsucesfully. If you put a jumper wire in the initial set coupler or unplug the bac from it harness and the car dies, you need to raise the idle up.

Anyways i have the same car as you and i live pretty close, you wanna like... you know. How old are you, Are you hot? jk

 

Need more info. When the CAS was replaced, did the person who did it: 1. Know what they were doing. 2. Time it correctly when they were done?

I think I would start with the timing issue, and progress from there.

 

Against my better judgement, I am going to involve myself in this thread.

First off, idle hunt is usually a culprit of a mis-adjusted TPS. Easy to fix, and easy to search and find the method of setting it. Second, typing with the caps lock on is kind of grating to alot of us that spend alot of time reading and helping others on this forum, so please, turn it off. Lastly, it may come as some surprise to the guys here, but some girls CAN work on thier cars. My girlfriend happens to drive an FC, and does all the work on it herself. So dont be so freakin amazed that girls can work on cars.

Or vacuum leak, or bad BAC, or bad idle solenoid, or..............

 

Eh, not so much.. Vacuum leaks GENERALLy cause high idle, or no idle at all. I am not going to dismiss the fact that its possible, its just extremely unlikely. The BACs when they fail, just stop working, so I wouldnt even look at this as culprit. And the Idle Solenoid? Okay.... What would that be? The PS idle up for the TII? The AWS system? Be more specific.

 

Disconnect the idle solenoid and see what the car does. Hmmmm, the idle hunts up and down.

 

Why not step through the idle setting procedure in the manual? It is pretty specific and can help isolate the problem.

 

Anyways I would definately start by checking the timing... If someone replaced the CAS incorrectly, it would cause every problem you're having...

 

What is this solenoid you continue to speak of?

 

Thread pruned for non-topic posts, post ******, and leg humpers.

Keep it on subject here or this thread will be closed.

Post ****** and Leg humpers please only post in the lounge as they have no place in the 2nd gen RX-7 Technical section here.

 

it is the otherway around for FCs.

on FC, or any car with an AFM, the rpm will drop when a vacuum leak is present.
Two things happen, one, there is more air going to the engine, two, the afm is detecting less air going to the engine

 

Actually, small vacuum leaks will cause the idle to raise slightly due to a leaner mix. Check this by removing a vac line. Ive proven it time and time again. Once the vaccuum leak gets to a certain size, the car will just not run anymore.

 

you have a standalone, dont you?
when you pull your vacuum line, your ECU will see the extra air and give gas to compensate for it...

did you try it on a car that has an AFM?

i know on my blue bullet, the car drops to a 500ish crappy idle....
