Why does my car **** so bad at low speeds?

[ViperperfectionGTS]

My 96 GTS jerks uncontrollably at low speeds in 1st gear. It has nothing to do with my driving techniques. This is my 4th Viper...I remember that my '93 acted the same way. It is definately the car. Has anyone else experienced this? Does your car do it? Is there a fix? I can release the clutch as smoothly & slowly as possible & it still does it.

Any suggestions?

Thanks very much

that fault can and will get u alot of differant answers in this question, cause can be many things.

 

[mjorgensen Woodhouse]

New motor mounts and trans mounts would help a ton. Call if you want to try them. The other cause could be excessive backlash in the gears.

Someone said something about having to "align" the throttle cables on both sides of the block. I may be stupid, but I only see one.

 

[bluesrt]

that guy is smokin something..

 

[ViperperfectionGTS]

Ok, I just wanted to make sure.
He said that the pedals pull two different throttle cables & if they are not "aligned" the car will ****, etc.

I have been looking for a second cable...Just wanted to make sure I wasn't losing it.

Thanks

I had the same problem on the 94 for years but it was fixed (mostly) when I took the car in for a full tune up. he said he adjusted the throttle "bolt"? But I had most of the engine and fuel system and trany and just about everything cleaned out so its hard to say what fixed it. But I can say it feels like a new car now.

It depends on if it's a Gen I or II. Your car is a GTS Gen II which only has one cable.

Does it only **** when it's cold? If so, then its just because your clutch is cold then it goes away after a while.

FYI the gen 1 has DUAL THOTTLE Bodies

that means 2 cables (one on each side).

ya know i drive an 03 and mine does the same thing but not all the time i thought it was me but its not

take it to kawasaki shop and have the carbs syncrinized...

 

[J&R3xV10]

one sure fix is more gas.

 

[ViperperfectionGTS]

The more gas thing certainly does the trick!!! HA

Think about it this way, both gen1 and gen2 have two throttle bodies, but, the gen2 only has one throttle cable. On the gen2 if the drivers side throttle body doesn't open first it will cause that jerky acceleration issue.

 

[ViperperfectionGTS]

IN that case...How do I ensure the drivers side opens first?

dont the gen 11 work together? one cable?

Can I call if I want to "try" them? If I like 'em, I'll send you a check.

Lotsa things can cause it. New plugs and wires can settle it down some. No matter what though, there will always be some lunging at low speeds. I usually slip it into neutral at slow speeds.

If this is really your Fourth Viper, you NEED to join the VCA and upgrade your status here!

"Lotsa things can cause it. New plugs and wires can settle it down some. No matter what though, there will always be some lunging at low speeds. I usually slip it into neutral at slow speeds."

Also could be: O2's, TPS, fuel pressure, re-setting the PCM?

"New motor mounts and trans mounts would help a ton. Call if you want to try them. The other cause could be excessive backlash in the gears."

Highly unlikely! "My 2-cents"

Just a thought:

Does your car have a light weight fly wheel as a mod? This can cause some jerkyness at low speeds in 1st gear.

 

[RobZ]

Almost any manual transmission equipped car will do that when idling/very low speeds due to gear/u-joint/overall drivetrain slop. Once it gets into a rythym you need to depress the clutch pedal or apply more throttle to break that rythym.

Why does my car **** so bad at low speeds?

Your car's ability to communicate its feelings to you are limited. As a long time automobile whisperer I can assure you that your car is merely expressing its resentment, frustration and hostility at being driven too slowly while in gear. You need to make up for this abusive behavior by tracking the car.

You're right in some respect regarding bushing compliance, yet the significant factor are the springs on the clutch disc in a manual transmission car. The crankshaft and the transmission input shaft can twist axially in relation to one another due to these springs (to absorb engine pulses as mentioned in another post), promoting a bucking effect at low rpm especially if you give a little gas then let off then get back into it, the springs will create a bouncing effect having an engine that can create low end torque including diesels. You can get a tougher aftermarket clutch disc or a disc / clutch assembly without springs, yet there will be more neutral gear rattle.

PS - That's my Canuck 2 cents or US 1.65 cents at the current exchange rate which is worth less then Chucks.

FYI the gen 1 has DUAL THOTTLE Bodies

FYI the gen 1 2 and 4 ALL have Dual Throttle Bodies

Gen 3 has One Throttle Body

that means 2 cables (one on each side).

Gen 1 has 2 cables

Gen 2 has 1 cable with a rod that connects the two TB's

Gen 3 has 1 cable

Gen 4 is electronic

95% of the time, the **** can be found just aft of the steering wheel.
