The engine should die. If it doesn't, you've got a vacuum leak that must be addressed before you proceed with the rest of the tests. 3) Once the engine coolant is above 90 degrees F, you can proceed to test the fast idle valve. Start the engine and remove the vacuum line on the lower portion of the throttle body. Check for vacuum.
1. Start the engine and let it warm up until the normal working temperature, that is when the radiator fans start working. 2. Switch the engine off and wait for 5 seconds. 3. Turn the ingition switch until the indicator lights turn on, and wait 3 seconds. 4. Engine specs: 5.7 Mercruiser EFI Stern Drive, Bravo III. Engine serial number 0M033393. Throttle body injection. The symptons are: When I start the engine from cold, I allow the engine to warm up at idle. This goes smoothly everytime. When I rev up the engine, either in neutral or under load, the engine works fine.

Also Know, what is engine surge or hesitation? Hesitation Definition – An engine hesitation is an interruption of continuous power during acceleration. When a engine is hesitating it will cause the car to lunge or surge which will cause a sudden jerk as the car slows down. Engine specs: 5.7 Mercruiser EFI Stern Drive, Bravo III. Engine serial number 0M033393. Throttle body injection. The symptons are: When I start the engine from cold, I allow the engine to warm up at idle. This goes smoothly everytime. When I rev up the engine, either in neutral or under load, the engine works fine. Storm surge is an "abnormal rise of water generated by a storm, over and above the predicted astronomical tides," according to the National Oceanic and Atmospheric Administration (NOAA) I would like to have this fixed permanently, and not just the symptoms treated for a short time A dead injector will cause the engine start and operate when it is cold but not when it is warm. The hesitationor choking seems to only be upon acceleration from an idle/stop when the car is hunting idle or surging during idle. When up at speed and with RPMs above approximately 1500 rpm there does not seem to be any hesitationor choking either. I have a 95 hoe 4x4 with the 350 TBI and on a quick throttle push it has like a 1-2 hesitation before it takes off when the engine is warm and the check engine light comes on. I've already changed the cleaned the thriller body, changed fuel filter, spark plugs/wires. The injectors look like the are spraying good. Turns out there are two very common and easily correctable problems with tbi. Symptoms: Idle and WOT acceleration seems normal 100% of the time. Hesitation seems to happen the most, when getting on the highway via on-ramp, under medium acceleration, meaning not full throttle downshifting, but somewhere in the middle, where it stays in a higher gear, but the transmission is on the verge of downshifting.
Here are some: Stalls at idle, stalls when I put the clutch in, stalls when I turn a corner, misfires, surges, no power, cuts out, no power at top revs, runs rough, etc. It may well be that these events are the hesitation & stumble problems described in this article. There are more than 33 items, which if faulty, that can cause engine hesitation and stumble problems. 3 Basic Causes of
Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle. The problem often means the air/fuel mixture is not being properly enriched or is going lean, or the ignition system is weak and is misfiring when the engine comes under load or the air/fuel mixture goes lean.
The engine when idling hesitates a couple time a minute, drops to almost 0 rpm and then surges and returns to idle speed. My local Indmar service center (in Green Bay WI) has almost replaced every control part on my engine. they have given up and tell me their only option is to replace the engine entire although they admit the engineis ...
Tach surges up about 500 rpm and back to idle about every 3 seconds. Probably happens once or twice a week. Doesn't seem to matter if engine is hot or cold. Engine stumbles from idle . Tach drops down from idle to nearly 0 for less than a second and the engine stumbles like it will stall but doesn't. Usually happens as a single isolated.
A broken off lever will allow the engine to operate dangerously at wide open throttle when throttled up. Or, if the governor cross shaft (the shaft that protrudes from the block) gets bent due to rough handling of the engine, and if it's not bent too bad, it can be straightened with a small hammer. (It's made of mild steel.)
