ENGINE IDLE

[EXPLORER]

Okay any and all ideas will be greatly appreciated in this matter. My girlfriend has a 2000 Bayliner Capri with a 5.0 carbeurated v-8 in it. The engine will not idle. When you start her you have to really give her some fuel then the engine revs really high. You try to back off the throttle and it will die. We have treated the fuel and such and we are getting ready to run it some more, but, it will only run wide open. A lot of people keep saying the jets are clogged. Is it also possible that the throttle linkages are loose? Is it possible the carbeurator is "stuck"? What are some possible scenarios and remedies here???? Any information will be greatly appreciated, feel free to e-mail any information that could be some money saving ideas here.....Thanks much!!!!!!

I had this problem too, the electric choke wasn't working because the wire from the alternator fell off. You may also want to look for vacuum leaks and possibly rebuild the carb.

Im with mckenzie, Its starving for fuel. Check the jet's and the float bowl. check your fuel filter, even if there brand new.then check your fuel injecters. YOUR NOT GETTING FUEL.<br /><br />Suzuki40

Remember 4 stroke:<br /> Intake<br /> Compression<br /> Power<br /> Exhaust <br />You need air and fuel on the intake stroke<br />You need good rings to seal on the compression stroke.<br />You need fire from the spark plug to ignite the air fuel mixture on the power stroke<br />You need a unrestricted flow for the exhaust stroke.<br /><br />Suzuki40

Re: ENGINE IDLE

It's safe to say it's carb. related. Possibly the low speed jets are gummed up but I'd check the choke like McKenzie says. It's an easy check where the jet clearing will involve 'kitting' the carb.
