i have a 2000 camaro I recently bought for $850 I replaced the ignition module because it was messed up the guy drove it like that for about 9 months than it set for 1 year,
it ran fine for about 30 days then it started to mess up i havent drove it alot i have replaced the air filter, because it bogged down when i gave it gas so i thought it needed air, the spark plugs and wires have been changed by the guy i bought it from,
what my car is doing is, it idles wiered it goes up then down, when i go when i take off it jumps like its missing gears or something but its a standard when i go about 60 it jerks like its not getting gas or downshifting but im not shifting at all
if you can let me know something that would be great thanx in advance.

how much would it cost to do a diagnostics test and will it tell me exactly wat is wrong with it
