5.0_GT

Well i got it all together and running again, but iam having some issues, when i take off like normal from a stand still the back of the cars wiggles side to side for second untill you get going, also when you punch it the back end tends to side to side for second, if you take off slow its fine but any type of power the back end and will go side to side for for a few seconds until maybe 15 mph, thats one problem

the other is engine it idles like a champ maybe a little vibration but it idles great, but if you nail throttle really quick and let off it back fires allot and sometimes shoots out dark grey smoke, to me it seems like its over fueling but i like second opionions, well let me know what you guys think

well traction is ur swerving issue. get some thicker and stickier tires. warm em up before u launch too.

if i dont warm up my tires i go side to side up untill about 30 mph.. im also pretty close to bald tho

as for the smoke.. sounds like ur rings or valve seals. comes from under the hood or pipes?

well the thing is iam not launching the car, its a complete stock 5.0 with a motor that has 61k on it, this is just starting out normal no hard luanching or nothin, its like walking side to side, the smoke is a dark grey like a slight over fueling

check the rear suspension and make sure everything is tight, the gray smoke is fuel, maybe to much
