Could be a number of things.....Is your check engine light on?

 

Probably another spider problem... Do a search on CPI INJECTOR for troubleshooting info... The easiest way to tell is check your oil level, if you are leaking fuel it will be overfull...

 

the check engine light at first didnt come on untill i was sitting at a stop for over a minute and the codes that were displayed were ignition control error and map sensor low sig. and egr valve error. and the oil looks like two quarts over filled and not onehundred percent sure if it smelled like fuel or not. then i checked the spark plugs and there fouled and i could take them out by hand ( they were loose before i even touched them).

As stated very clearly in the Forum rules, creating more than one user account is prohibited. I have removed your account under the name chevy4.3. If you have not bothered to take the time to read the rules, I suggest you do so now.

 

I had the same trouble, but replaced the fuel pump and cleaned the egr valve and it cleared up. You may also want to look at the router and distributor cap.

Good luck!
