View Full Version : Slow start off the line

12-04-12, 08:23 PM
I have no immediate acceleration off the line, like it goes, but I couldn't lay any rubber (http://www.youtube.com/watch?NR=1&feature=endscreen&v=2_xlzgBUe7Q) if I tried, I did a bit of the Google, and I found this link (http://wiki.answers.com/Q/What_could_cause_a_1998_Cadillac_Catera_to_take_of f_very_slowly_when_you_floor_it) and this link (http://www.fixya.com/cars/t9291270-dont_want_accelarate)

Does this make any sense to any one? Would my TCM be going or is gone? What else could be causing this?

Also I found out that a piston is misfiring, could this be the issue with the acceleration not being there ? Also the plugs and spark plug wires have all be changed recently with new ones. How do I fix a misfire ? is it fixable ? Should I start parting this car out ?

Hay, I can only tell you what I did, it may work for you or may not, check and replace the fuel filter first, if that dosnt do it than the fuel pump, as far as the missfire, did you replace the Ignition Coil, when you did the sparks and wires, they all should be repace at the same time.

best of luck

Thanks for the information I will look into getting the fuel stuff figured out first before I go ripping into the engine, the last guy I got it from said as soon as it misfired on him he replaced all the 'plugs and wires' so I'm assuming he did not replace the ignition coil as it should have been.

Now is it best to replace all ignition coils even though one piston misfires? Is this precautionary fixing? or would I be better off to replace them one by one as they misfire?

But otherwise it should have some good pick up off the line? I'm not wanting to do mega burnouts or anything, I just want some decent acceleration off the line.

Also for the transmission would one of these (http://www.autopartswarehouse.com/details/QQBMWQQ328iQQFramQQAutomatic_Transmission_FilterQQ 19962000QQFFFT1149.html) help with the slow changing of gears (mainly 1-2nd gear.) I would like to take care of this car as much as I can with preventative replacement and what not.

the slow shifting from 1 to 2 is a easy fix, and is common, it needs a trans fluid change, and filter change, here,s what I did, I got the car leveled between the street and my driveway, got under the car, remove the tran pan, clean it, replace the filter, then got a hose that screws on quart bottles at autozone, and had someone hole the bottle upside down in the air while I put the other end in the drain pug, fill it up till it started to come out, then screw the plug in but not tight, started the car, move the stick shift up and down all gears then turn off the car and check the level again at the drain plug, if it need more I added, if it leak, I let it till it stop, remember the tran holes 7 quarts, you only replace about 1/2 that amount when you do this, ( about 3 1/2 quarts) the rest is in the tran, so I did this 3 times over 3 weekends and my tran runs smooth.
One big note, you MUST have the car leveled when doing this, I got a long leveler and lay it on top of the car, center, its as close as I could get it without going to a shop
