\'90 Chevy 350 cold start
Hi, All- New user.
I have a '90 chevy 1500 with a 350. On a cold start, the engine runs rough with the RPM's rising and falling from about 200 to about 1600 with a rythmic vroom, vroom, vroom.
The problem gets worse as the outside temperature gets lower, and is almost non existent at 80F. However, if I try to drive too soon, even on a hot start, the engine bucks and hesitates. both problems last about 30 secs.- longer in cold weather. No codes are being set......Any ideas?
