    stumble when turning right

    this issue still isnt solved and the shadow has been sitting for a while. 2 days ago i drove the car to a mechanic to figure out this issue and the damn thing ran great and the scanner could not pikc anything up.

    yesterday i took it for a boot again for a good half hour and is started to buck and jug when ever i turned right.

    if you search my name in the help section you'll find ive had this issue for a while and that it develops over time from stumble onyl when turning right fast to stumbling whenever i take any turn at any speeds.

    there are no codes and the fuel pressure does no dip but rather bounce from 40-60psi when bucking

    Well, I feel hurt,

    To me, sounds like either a fuel load issue in the tank-how full is the gas? or go over your wiring harness, sounds like something could be rubbing on right turns causing your issue.

    dont feel bad, pierre (mechanic friend), lives 5 minutes(no need for a tow ) away from me and he said he can take a quick look at for free. As always though the cars we have run great when its time to see the doctor. Just like my old Daytona
    Once/if this issue is fixed i got an alternator tension issue that i give up on

    Only does it when its warm
    It doesnt matter how full the fuel tank is as it does it even at a full tank
    fuel pressure doesnt dip
    no codes


    it has an aftermarket sound system that MAY be the issue. Reason why i say this is because it didnt stumble when the sub/amp were out. This could just be a coincidence

    Get it warm, then wiggle the wiring harness and see what happens.

    A friend had a similar issue, Drove him nuts... His issue was the wires going to the coil were pinched in the motor mount area and would ground during cornering.

    Re: stumble when turning right

    Two possibles.
    Neighbors son's car blew the wiper fuse whenever they were on. My mech checked found nothing wrong and replaced the motor. drove it, no probs.
    Kid picks it up blows the fuse in first rain. His dad goes psycho and call my mech every name in the book. Neighbor's nickname is now Psycho man.
    The long and short of it is the sound system was on the wiper fuse. The mechs like their hearing and never tested it with the radio for the deaf at full blast.
    2 A tc owner had you prob and a bad pass engine mount was causing the problem. Don't know if the ground wire or the harness was being pulled a little.

    ^^^^^ Yep... The flex caused the coil wire to ground.

    Re: stumble when turning right

    3 suggestions...

    i) Does this only happen in the rain/wet road ?
    Had cars that like to soak the belts turning right in the wet or when you catch a puddle on that side.

    ii) did you check for the steering binding anywhere? Rusted up tie rod ends or inners, rack falling off, etc, might make the pump work real hard and try to stall it.

    iii) Check your oil, overfull it could be flooding the bottom end on rights.

    Re: stumble when turning right

    Does it completely turn off and then fully restart again on these turns?

    Re: stumble when turning right

    does it whenever, even when dry or full of gas.

    Ill check the coil wire and see if i can figure out were the installer installed the sound system....i know he grounded the sub behind the back seats on the floor.

    Hmmmmmmmm, wonder if he pinched a wire when he did that?

    Re: stumble when turning right

    Had some time today

    got the car warmed up and CRANKED on the wiring harness, wiggled all wires and the car never stumbled. Yes, i did notice that a section of the wiring harness runs under the pass side mount and looked pinched against the strut tower. I paid extra attention to moving around the wires there and found nothing.

    Took the car for a boot and did a few 180 right turns. Aside from noticing that a shadow handles better than a daytona, the car ran like a champ.
    But I did notice one thing: the fuel tank gauge would dip a 1/4 tank when turning left or increase a 1/4 tank when turning right. Also i could hear the fuel splashing around in the tank ALOT. This to me doesnt seem normal.

    Went home and cranked the the wiring harness again and found nothing.

    I just remembered that this issue started happening AFTER i shifted the gas tank over to install the TU 3" exhaust system. the gas tank is a little dented at parts.

    Can anyone tell me where the pick up is located in the tank?

    I guess all thats left right now is to install the sub/amp and take it for a boot to see if it stumbles
    PS the remember being told by the installer that he hooked the system up to the ignition.

    Re: stumble when turning right

    In that case, I would take the tank out, it could be all that bashing, somethings come loose and its either pinching a power wire-had that happen to me on a Camaro, took me months to figure that out, or the fuel pickup is being plugged.
