Weirdest Idling Problem...

[UpbeatFish]

After Reseting the timing for my car it was idling and driving perfect. the next day we gave her a tune up with new spark plugs , wires. after we installed everything back together it was idling very weird. we found that disconnect 3 and 4 plugs from the spark plug, it doesnt respond at all. but the injectors are new....

i got these fallowing codes :

14 Ignition Signal

Diagnosis
No "IGF" signal to ECU "A" times in succession.
A = 6-8 (7M-GE)
A= 3 (7M-GTE)
Trouble Area
Igniter and ignition coil circuit

21 Oxygen Sensor Signal

Diagnosis

22 Water Temp Sensor Signal

Diagnosis

24 Intake air Temp Sensor Signal

Diagnosis

43 Starter Signal

Diagnosis

Trouble Area

52 Knock Sensor Signal

Diagnosis

all together is: 14 21 22 24 43 52


i recorded a video to give an example of my problem. thank you everyone.

Pull the EFI fuse, drive the car and re-check the codes.

youtube is taking for ever hold your ponies

videos up

guess this was as weird as i thought....hmmm

I do what this guy saids to do..............make sure you put the EFI fuse back in first though.......:biglaugh:

 

[grimreaper]

that sounds horrible out the tail pipe!

 

[adampecush]

did you verify the correct installation of the spark plug wires?

Also, clean up that rats nest of wires coming over the top of the engine...at least wrap them in some split loom.

i actually undid that the previous owner did a horrible wire job and i wanted to see if anything looked wrong. it all checks out though...

im doing that right now.
so i pulled the efi fuse out and it didnt start as i thought. and after i put it back in , drove it a lil . turned it of and back on the on switch and it gave me these codes 14 21 22 43


so 24 and 52 are gone


it still sounds and drives the same.
i press on the gas and it barley wants to move..

 

[jetjock]

Not that it matters now but he meant pull the fuse, put it back in, and then drive the car...

Why were the plugs changed if it was working ok?

Have you tried reverting back to how it was and then re-testing?

because i just bought the car and of course it needs a tune up


and yes i tried everything. sprak plugs, with new wires. old wires with old spark. new spraks with old wires. everything. same thing...wtf

 

[noel]

well lets see new spark plugs and wires ask youself what does the wires connect to ? coil Pack change that and retest ...just my 3cents...

the coil is fine already check read the 1st posting

 

[noel]

OOPS my B lol so the wires are new plugs and coil pack are good ....i dunno u got me!! if i were u i would start curseing and throw a lil fit punching the wall and stuff!!:aigo: double check your grounds...

Can you make another video? Surely the helicopter is not still hovering over it. LOL

Mine sounded like that until I fixed both my coil pack, and reset my timing. Check your timing marks. Verify that the timing marks are lined up when the the crank pulley is at "0". Also, verify that you are actually at TDC while it is at "0". Also verify that your cam gears are installed correctly. The dowel pin should be in the center hole, both on the gear and the cam itself. Then reset the CPS once it is all in the correct place, if it is not already there. Once all of that is done use a timing light to put it at 10*BTDC. If the CPS is installed correctly, you should be able to fine tune in both direction.

okay i will do this tomorrow

i just want to say thank you everyone for your help!!!

A video really isn't necessary. With all of those trouble codes, you have some major issues. My money is on your wiring harness. I can almost guarantee that is what is causing 95&#37; of your problems.

You probably bumped the brittle old wiring as you were working, and now it's not making contact like it used to...you have a lot of codes that will affect the way the car runs. I would start inspecting the wiring. If the copper wiring is corroded and green (like most supras these days) you really should replace the entire harness.
