Here is the deal I recently bought a 92 lumina with the 3.1 V-6 in it. On the way home it ran great. However AFter it sat for 1hr I went to go for a drive. It was running good. then 10 minutes later. I started having a really rough Idle but not stalling.
On the way home from when i first got it I could hit 60 in seconds. Now Once I get to about 40 it doesnt want to go. It Like shuters or vibrates.
Just dont get It. I changed Plugs Oil and Wires bUt It still Does the same thing. Now today I went to drive it Did real good for a while then after a little bit same thing.
ANY IDEAS??
Please help Its the only car I got
