Answer 1

You need to check the fuel pressure regulator. Probably leaking fuel into intake manifold.

Answer 2

It sounds like you've either slipped a timing belt (this would cause the car to backfire when trying to start. It probably is getting too much gas, because of the timing thing, hence the stalling. Your car probably has a rubber (not actually, but I mean it's not metal) timing belt and it has stretched and jumped a tooth. Usually, the timing belt is to be changed at 60,000 to 75,000 miles. This really needs to be checked, if it is the timing belt (can tell by checking the timing) it can ruin your engine. it's very serious.

Answer 3

Sounds like a clogged fuel line. Change out the Fuel Filter. In fact a whole Tune Up I'd say.

Answer 4

i comprehend all the different solutions refer you to gasoline appropriate complications and also you need to purely eliminate gasoline first yet a failing coil may reason similar indicators. at the same time as a coil starts off to fail, it truly is going to from time to time enable a motor to run for a couple of minutes before death - this can make you imagine it truly is a gasoline problem at the same time as it truly is somewhat a lack of spark. once you've a spare coil - swap it over and note what takes position - you're stunned.

Answer 5
