0-60 in 12 seconds?

[Feceger]

Hi there, A little while I posted a thread about my car, a 1987 325i slushbox. It was being super sluggish and was really disappointing. I did 0-60 in about 12 seconds... ya right
Most people thought it was a restricted cat, so i got a custom exhaust put together.... and its no better.

So Rev, why is my car so slow?
-Dont just say its because its auto... I know they're faster than that.

Few things i've noticed
-Slight rough idle
-Dirty injectors (cleaned them)
-Smells like its running rich (dont know how to go about fixing this)
-Trouble starting when it sits for an hour, always starts but it has to turn over for a while first. Starts fast cold, and starts fast hot... Just not warm.
-As soon as I let off the gas and i'm stationary, the revs drop to like 300 and it feels like its gooing to stall out. This only happens when i blip the throttle at idle.

Any ideas would be greatly appreciated!

-Will

my car goes 0-60 in like 10 seconds cause 1 2 and some of 3rd gear is spinning the tires...

Nice! Unfortunately. Mine is just slow.

are you running an oxygen sensor with this "custom exhaust"? problems with it can cause crappy running and/or running rich. running with no oxygen sensor will run rich. idle problems sound like a vacuum leak. any hoses missing or leaky?
