Dodge: 88 Plymouth Voyager

I have a 88 Plymouth Voyager with a 2.5 4 cylinder. The problem is it runs
very rough. The #4 cylinder loads up with gas. I changed the whole throttle
body thinking it might of been the injector. It'll run great for a while
then load up and run rough..

I've done a complete tune up on it, Changed the MAP sensor as well as the
throttle sensor. Someone told me it might the fuel pressure regulator??? If
so where is that located!!

Any ideas??? TIA......Brian

if the regulator or fuel injector was bad on this engine it would cause all
the cylinders to be flooded not just one, you need to take a look at why
the fuel isnt being burnt in that cylinder......compression, spark all
that
