i have a 91 vette with a l98 and its idling kind of rough so i did a complete tune up, cleaned the throttle body and timed it and it rand better but still a little rough. any suggestions on that. also when i put the car in reverse or drive it sputters really bad for about a second then shuts right off but will start right back up. any suggestions will help. the car has been sitting for a while and it ran good before it was stopped

 

hey im new to the forum and on all the threads under everybodys replies they have a catchprhrase or one-liner that is unique to their profile. My question is how do i get this on my profile? Oh and one more thing, my profile says C-Main Driver. For now its true but if i get better how do i change that? Please help.

Don't know a lot about the later vettes,but have dealt with an very similar problem on 2 occasions lately. Both times the solution was to change the fuel pump but I believe a replacement,thorough cleaning or simple removal of the strainer on the in-tank fuel pump would have probably produced the same result. Have you checked your fuel pressure during these episodes? Also I believe there is a fuel filter somewhere in the fuel rail,definitely one under the car. Have you changed either or both lately? Good Luck!

there is a fuel filter under right frame rail right behind wheel where lines turn 2 motor,and the back y pipe can cause these problems.
