Ok...so here's the rundown. I was driving home the other night and my car just up and started running like crap, RPMs dropped way low, car was sputtering real bad and backfiring when I'd get heavy on the throttle, within about 20 second of trying to do that just so I could get home since I was only about 5 mi. away...I couldn't get my RPMs over 2k, and they were real spuratic, jumping up and down really fast and then pretty much the car wouldn't get over 15-20mph and was still slowing down, so I pulled into a neighborhood shut it down got a ride home and had it towed the next day. At first I was thinking it was my fuel pump cause I ran out of gas about a month ago(yeah, I know, that's a job for women, but I had a brain fart) so I changed the fuel pump today with a brand new holley 255lph I've had for a little while....exact same problem. The only other thing I think it could be is the tranny going out on me, cause it's slowly been doing that where every so often i drops out of overdrive, or I'll be driving along and it'll drop out of gear. Anyone had this problem before? Need an answer soon, cause I don't wanna be riding my crotch rocket for the larger part of the summer here in Phoenix
