Carrera228 Posted January 6, 2004 Share Posted January 6, 2004 upon starting my car up in the morning, it runs very erratically, stumbling irregularly, etc. once the car has heated up after 20 minutes of driving or so, it no longer does this. any ideas on what this might be? there aren't any warning lights illuminated. i was thinking maybe a bad injector(?) by the way, it is a 93 LS with 122,000 miles Quote Link to comment Share on other sites More sharing options...
SKperformance Posted January 6, 2004 Share Posted January 6, 2004 Get a good fuel flush . One that uses a machine to clean injectors. It might be the cold start nijector being plugged which is common. ALso it might be you need to clean your throttle body to remove carbon deposits.

tansupplyman Posted January 6, 2004 Share Posted January 6, 2004 Use "BG 44K" before you take anywhere. go to Google and type this in to find out what it is---it is the best cleaner. Quote Link to comment Share on other sites More sharing options...
tansupplyman Posted January 6, 2004 Share Posted January 6, 2004 last one: I forgot----also clean your throttle body---this will do 'wonders'. Check on Curt's description on this--not sure where it is. Quote Link to comment Share on other sites More sharing options...
mig25 Posted January 6, 2004 Share Posted January 6, 2004 <_< When was the last time you tuned it up? Also it is a good Idea to clean the throtle body. I did mine and it was pretty gummed up. my 90 LS has 135K miles. If you have not yet tuned it up. It is time to get some Nippondenso Plugs, rotors, dist. caps, fuel filter, air filter , PCV valve.and wire set. I done all that inmy and runs like a champ.

UCF3 Posted January 6, 2004 Share Posted January 6, 2004 It sounds like the Fuel Injectors are getting clogged. It also doesn't hurt to pour some Dry Gas into the fuel tank, if you live in a rather cold climate zone, Quote Link to comment Share on other sites More sharing options...
tansupplyman Posted January 6, 2004 Share Posted January 6, 2004 Here is the thottle body cleaning site. http://www.lextreme.com/tb.htm Quote Link to comment Share on other sites More sharing options...
mig25 Posted January 7, 2004 Share Posted January 7, 2004 Would be a lot easier if you remove the throtle body, as I did. it is only 4 bolts and you need to disconnect the acelerator cable. but there is no chance of droping any debris inside of the intake manifold. The other way described on the link above is dangerous. If you drop anything inside of the manifol, you will have to remove the entire intake manifold Quote Link to comment Share on other sites More sharing options...

Carrera228 Posted January 7, 2004 Author Share Posted January 7, 2004 i couldn't locate the cleaner you guys recommended, so i called the local asian import shop and they said they use Redline injector cleaner. i picked up a bottle and am running it through the current tank of gas. i'll let you guys know if it's a success Quote Link to comment Share on other sites More sharing options...
