Question about Cars & Trucks

1 Answer

22hp v-twin intec B&S starts, runs & cuts good for 15 -20 minutes then starts to loose power, sputters & eventually dies.

Let it sit for 2-3 hours and I can do the whole process over again. Tried opening the gas tank cap, new gas, new gas & air filter, new fuel pump. No change. can you help?

The OHV engine requires periodic valve adjustment. Typically every 300 hrs.

Another possible cause is an ignition module failing at operating temperature. Run until it fails and check for spark at BOTH plugs.

My car is sputtering and dying. If I try to restart it, it will immediately go into sputtering/dying mode. If I wait a while an hour or so it will start up and drive fine.

When was the last time that the carburetor was stripped and cleaned? Also have you checked the fuel filter? Finally, the problem seems to come and go as the engine is run (and it gets hot) check that the fuel line and any electrical cables are well away from the hot engine as far as is possible.

The 04 van will occasionally act as if it is running out of gas and die. Will restart after sitting for a short while.

It could be a weak pump. It could be pretty old if you haven't changed it recently. To be sure, have the fuel pressure checked. Filters don't usually clog up and then start flowing again; once done, they're done.

Loosing power at cruising speed

Hi. I have two Dynasty LE cars, (a 91 and a 93). Both have the 3.3 litre. The 1991 had almost the same problem as yours except it would only do it once the engine warmed up, (similar to your freeway issue, given distance and time for the engine to warm up to operating temp.) I had it in about three shops before the dealer found an intermittent fault with the cam and crank sensors. I replaced them and now it runs just fine. I hope this helps.
