Hi DonCherry, you are man expereinced and knowledge.
>>Thanks, please don't say that, I learned lot from friends here, guys like Folks, carman, louji, and others I cannot remember the name. Most of fellows here are warm-hearted and nice.
Could you tell me the possible problem for following
sympton:
Everyday the car is first started (cold start), the car is powerless whatever pressing gas pad, it runs around 20 to 40KM/h , but engine speed could be high as long as pressing hard on the pad, it needs to be drived 5 or 10 minutes before returning NORMAL
>>You must have an old car. The problem could involve lot things, but you can figure out one by one.
1)Does car easier to start? Does it easier to stall? If so, basically need a cleanup type of tune-up such a new air filter, new sparks/wires/distributor cap,rod, clean throttle body valve, etc.
If not, the mixture is not perfect when cold, not a big issue for old cars.
2)Cylinder lose pressure because of wore out. Nothing can do on this kind of lose.
3)Transmission is old, in vintage status, or fluid is to dirty. So it is slower to response/up-shifting.(Assuming it Is automatic transmission)
I think first two are main reasons. If it is old car, just drive as usual. |
