Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

posting for a buddy of mine, saw this for myself riding in his car , good idle and starts up fine. But seems like slow left hand turns the car stalls, like when pulling into a side street. weirdest thing- cleaning the icv didnt help, but just wondering if anyone w\ 99 has seen this

POST 2Original post

hmmmm.... how many miles? AOS, vacuum leak issue?

POST 3 / ORIGINAL POSTEROriginal post

Hi Ferd hes got about 80K on the car, whats a good way of getting a vac reading ?

POST 4Original post

you can tap the vac line on the left side of the throttle body.... It stalls only on left turn? The only thing I can think of is the diaphragm on the AOS is bad and flopping around causing a bad vac.... wild guess.

Well, someone posted something similar a while back only the car would act up only when making right hand turns. I guessed, err reasoned it was a fueling issue. The owner took the car to a dealer and the tech took the car out and discovered the symptom appeared no matter which direction the turn. The tech did some other things and diagnosed the problem was with the throttle valve and this was replaced and symptoms were last I heard gone and have not returned. So, now I have two guesses.... 1) Fueling issue; 2) Throttle valve problem. Hey enough guesses I'm bound to be right, sometime. Sincerely, Macster.

POST 6 / ORIGINAL POSTEROriginal post

hmm all good ideas, ill let him know

POST 7Original post

What are you referring to as "throttle valve"? The 99 C2 being cable driven, I don't think there is a throttle valve? No?

POST 8 / ORIGINAL POSTEROriginal post

I think he was talking about the throttle body butterfly\valve- in general

POST 9Original post

Are you sure that UPS did not program the ECU so that it could only turn right. This is the policy for its delivery trucks now.

POST 11Original post

Ted Kennedy had an Oldsmobile that couldn't turn left, so he ended up in the water one night.
