cobra still sputters
 
Well guys im at it again. cobra still sputters between 2k and 3k rpms when warmed up usually after 30min of driving.

changed parts-
spark plugs (coppers)
taylor wires
dizzy
alternator (old one bad)
coil
cleaned t/b and MAF
timing at 14* All this done within last 3 weeks.

Could my gas pump be going out? watch vid. when the rpms jump up and down my foot is steady on gas pedal. Also mostly happens on 2nd and 3rd gear.

Sorry. Check it now.

Have you pulled any codes? Im assuming you have since I know you have been an active member here for quite some time and know we would tell you that first lol .

Just out of curiosity , does this happen at the same throttle position ? Im wondering if you have a bad spot on your TPS causing this. What does it do when you stand on it? .

Yes.. lol And yes. same throttle position. That needle jumping up and down is not caused by my right foot lol. If I just mash on it revs up normal and no sputter. Just when I cruise between 2k and 3k steady. My KOER has no codes but my KOEO had 3. One of which (disconnected Temp sensor) I caused by unplugging it to see if my fan was working (it was) but that did give me a cel until I plugged it back on and I had another that said something like spout connector not grounding? I have the codes at home. 3rd code was I think a 172. But as I drive I have no cel!

That spout connector code could play a significant role in your trouble. I would get a timing light and check your timing with the spout plugged in , watch the mark as you increase throttle , if it starts jumping around all over the place you may have a short in the pcm or spout circuit someplace.

So those codes on the KOEO can still affect my car even tho I have no CEL or no codes doing KOER test? I will try test later on after I get home.

I did the test and as i gave it gas the mark on balancer did not jump around. was pretty steady. Spout was also connected. This sucks! Could it be a bad spark plug? Remember i added the whole bottle of seafoam to half a tank incident. well i never checked for foul plugs. But weird thing is that car runs perfect until it gets warmed up.

so code was 212- ground short in spout connector

Js88lx 07-08-2014 06:58 PM

Maybe a TFI module going out?

Js88lx 07-09-2014 09:44 PM

opened up tfi.. looks good. Should my spark plug have oil at the middle like that? The top was dry but just thought it was weird.

If you're not getting any advance under throttle and the computer is saying spout connector, that's probably where I'd be looking.

Plug looks fine (new actually) to me. I wouldn't worry about the slide residue.

Js88lx 07-10-2014 09:42 AM

iv looked for faulty spout and connectors online but no luck. Any tips and pointers on how to check or look around the spout?

Maxwelhse 07-10-2014 02:52 PM

Not quite the same, but this is a guy repairing the issue on a Ranger with the same code and symptoms (if you watch the video from about the 1/2 point he describes the timing being exactly what your car is doing). He had a wiring failure. Unfortunately his Dog starts going berserk and its almost impossible to hear him talk, but you get the idea. He replaced the connector with a fuse (silly way to do it IMHO, but use what ya got I guess).

So... My short answer is to check your wiring over and see what shakes loose. If I absolutely had to, and simply connecting the two wire together works (I don't have any clue what is actually inside of the "spout"), I'd throw a scotch-loc between the two wires as a temp fix and see if it cures it. If it does, properly replace the wires (to me, that means solder and heat shrink) and connector and off you go.

ok.., well i had the icm (PIP) checked today when car started acting up while pip was warm since thats when the issue starts. i literally unplugged it outside autozone. 1st test pass.. 2nd test failed.. 3rd test failed. could this be my problem? Not sure what this means but the tester they used had about 6 or 7 lights that would either go green for pass or red for failed... it passed all green lights except 1.. the threshold light.? whatt?

Maxwelhse 07-10-2014 09:14 PM

I have no idea about the lights, but if the tester failed it I'd say its a bad part...

You could always take it to another store and have it tested again on a different machine.

Js88lx 07-11-2014 12:24 AM

im so dumb, sorry. I mean tfi not pip but as you can see i also put icm so i was half right lol, i meant icm/tfi. I hope thats the problem.

Js88lx 07-11-2014 12:28 AM

Ill prob just buy it and install it carefully and if it doesnt help ill just return it.

Maxwelhse 07-11-2014 01:19 AM

Sounds like a plan since it came up dead. Good luck!

Js88lx 07-11-2014 02:27 PM

Well i sapped out old one with new one right when the sputtering happened. Pulled over and did it on side of road. Started her up and she idled nice! Drove her and no more sputter, but 10 min later on freeway coasting at 2k rpm's it started but this time very very small stutter and only when i barely give it gas.., barely! Once i give it a little gas it stops sputtering..? OH man, looks like whenever i swapped parts it minimizes the problem but it doesnt go away. Im loading vid up right now, but its similar to the other one just lower rpm and smaller sputter.
