UPDATE:Engine shutting off, Ck eng lt code 17 ,erratic idle

[packrat427]

Well I am not going to hold my breath for a few days , Just got back from a drive , put it to the test and it did not act up at all , I drove it normal, that is when it acted up the most ..


I adjusted the TPS ???

I cleaned it the other day and it made no difference .
I unplugged it and it still did it yesterday ??
The only thing I did tell before today was the decel thing ,it worked better , it did not feel like you were tapping on the gas pedal while decelerating .
Which I know that the TPS sends a signal to the ECM and regulates fuel to the injectors , and if it is out of adjustment it will send burst of fuel and make idle erratic .and not send the proper fuel delivery .
My pump still runs key on - engine off , but not everytime though ??

This car has consumed 5 days and my entire weekend :x
I don't know if I should shun it or give it a treat ,maybe a bath after the engine compartment has been drenched in gasoline ?????
Match or a bath :roll:

:lol:


Just kidding I would not do that to my baby ,not that I did not feel like it .

You only burn them IF they make you so mad, and you CANNOT get it to run! :twisted:

I really think I may have had more than 1 problem , with the code 17 = O2 and the fuel pump running when it should not ,the shutting off feeling at speed, and the unstable engine speed at 1,500-2,100 rpm's .
Fingers crossed . :lol:

[packrat427]

So far so good !!!!!!!!
Drove it all over yesterday and to work and back today , not one glitch
I still can't believe that the lower spring rod inside that TPS switch was causing all my problem .
Well at least I have a fresh fuel pump and a bunch of clean connectors :lol:

[studdyhalllooser]

just curious...how did you adjust your tps? been a while since i had to do mine, thanks,
Jay

[packrat427]

I just adjusted it till it came out of it , I only moved it a hair , must have got out of spec from wear , I know it prolly need's checked right .
I know the timing and idle speed need to be right , Then you unplug the TPS harness and use a ohm meter to plug into the terminals on the actual TPS .
it show's a early and a late model plug.
Late shows the ref on top sig in the middle and gnd on the bottom
Early shows the same ,just a different style plug .
Install a feeler gauge in between the throttle lever and the adjustment screw near the dashpot .
0.02inch (0.5mm) with the ohm meter in the gnd /sig terminal it should show continuity with the ohm meter in the ref/sig term it should show no continuity
with a 0.027 inch (0.7mm) feeler in there gnd /sig -no cont ..ref/sig no cont.
wide open throttle gnd /sig no cont. .. ref/sig shows cont.

Loosen the TPS adj screws and move it into the correct range with the feeler gauges and tighten it down.
I hope this helps

So far so good , I have drove it for a week now ,and I just got back from a 100 + mile trip this evening , No check engine light and no buck jerk /shutoff stuff ,and I did have the Festiva's most unfavorite passenger with me :lol: :lol:

[packrat427]

I just drove another 100 miles this morning to go see a Festiva ,still no problems .
She still has it in her ....................50.5 MPG !!!!
I thought I lost some mileage ,NO I did not

[wrestler3025]

I hope I get 50mpg on the way to Minnesota/Wisconsin tomorrow. I would think that I should....right :wink: I'm going right through Illnois on my way to cheese head land. We are going to be driving right past you on 57 & 74

[packrat427]

Cool, I hope the best for you , too bad you were not coming West on I-72 .

I hope that was your problem !!
The wire .

[wrestler3025]

Nope!!! :evil: Well, I'll make it there though. We are leaving in a couple hours. I've got a whole toolbox of extra parts just in case, as well as my tool box. If we were going that way I would stop in, but I believe we would be there around 6-8 am so it would be a bit early anyway hehehe. Wish me luck!!
