vibration?

IM not sure wuts going on with my car. it was driving fine then it started vibrating. and my service engine soon light came on, and it was flashing. my oil pressure n temp were fine, and it idles and when its in nutraul it doesnt vibrate. Anyone know wuts going on? talk to my mechanic seems liek possible u joints but theres no sensor on them for the engine light., and no i dont have a flat tire, if ur thinking im completely clueless.

have the car scanned for codes to see what code its throwing and then go from there

yea its at my mechanics right now that wut there doing

that should give them a very good idea whats wrong or atleast point them in the right direction

bad plug or wire mabey. can you give more info on what you have (year manual/auto, ect...)

A bad U joint will usually "pop" while putting the car in reverse, or going from reverse to drive. Thats a warning sign they are about to go out. With the amount of vibration your talking about, it really sounds like anything, but probably something in the driveshaft area. Maybe a broken motor mount or possibly somehting as stupid as an egged tire, but that wouldn't make the SES light come on. Look in your manual. It should tell you what a "flashing SES" light means as opposed to one that stays on constantly. Could possibly be somthing in the fuel where the cars getting it irregularly and its causing the car to "shake", but you would notice bad performance. As everyong else said, wait on the code to come out (even though you could have got the codes pulled for free at autozone in a few minutes =) and get back to us.

a flashing SES light only means that the proplem is happening again. i had that problem with mine when i had a melted plug wire. seriousely check your plugs and wires. thse sound exactly like the symtoms of the fireing system. (assuming from your name) you have a 98 camaro possiable an ls1. you got luckie it wasnt the "opticrap" like on lt1 systems. i'm just fearin the day that breaks on my baby.

its not a ls1 sorry only a 6 hear with a stick but thanks for the help and its getting looked at right now, and a plug wire is a very good possiblity.
