Help, Guys!
I was driving home from work today when all of the sudden I tried to accelerate and i heard this real loud knocking sound and the car wouldn't go anywhere. It doesn't stall, and if I go real easy on the gas it's fine, but when I accelerate normally it seizes and knocks! What the hell is it!? It scared me....you can only imagine the traffic I was in. God I almost had a heart attack. If you guys have any ideas please tell me....

Re: Help, Guys!
Yup, check oil pressure first. If its just a knock when you first accelerate and slow down. It could be U-joint , tranny mount or rear issue but from the sound of it. It sounds like a major engine issue such as a spun bearing.

Re: Help, Guys!
She's got fresh oil, I changed it yesterday. I checked the plug and the filter, no problems.....If I hit the gas easy it doesn't happen, only when I slam my foot down.

Re: Help, Guys!
not oil,as in clean. Oil as in pressure. How much oil pressure is she making cause I actually spun a bearing on my original engine in my car. The same exact day I changed the oil in it. So that doesn't really always matter as much as some people think.

Re: Help, Guys!
i had a similar problem with my camaro one time, when i accelerated anywhere near hard, there was a loud knock and the car sputtered hard.. replaced the o2 sensors, no more problems.

Get under the car with a jack and jack up the trans by the tailshaft, look to see if it lifts off the trans crossmember mount at all, if it does,,,get a new mount.
