armyastro Posted March 18, 2006 Share Posted March 18, 2006 i have a 1993 sc300 and i went to work this morning and all is fine.... but i go to leave and it stumbles and jerks pretty hard when you barely press the gas in i thought it might be the fuel but its not i changed the filter too plus checked the timing??? i think it might be the cat conv's cause i think they have a slight clog cause i can smell it sometimes but i am stumped??? anybody have any suggestions please?????????

SKperformance Posted March 18, 2006 Share Posted March 18, 2006 you may have a bad injector a dirty tb ,maf or intake need to also check the rotors and cap Quote Link to comment Share on other sites More sharing options...
armyastro Posted March 18, 2006 Author Share Posted March 18, 2006 i just changed the plugs, wires, and cap and rotor last week and it has been running fine , however i did just fill my tank up with 92 premium gas so maybe i got bad gas???? i hope that is all it is Quote Link to comment Share on other sites More sharing options...
SKperformance Posted March 18, 2006 Share Posted March 18, 2006 Anything else you forgot to mention you fixed or changed? Quote Link to comment Share on other sites More sharing options...
armyastro Posted March 19, 2006 Author Share Posted March 19, 2006 ok another update.... i put headers on it and eliminated the first 2 cats and put new o2 sensors on it and it seems to be running pretty good and in 2 days i will be getting new exhaust and mufflers put on it so we will see how it goes Quote Link to comment Share on other sites More sharing options...
armyastro Posted March 20, 2006 Author Share Posted March 20, 2006 ok well i took the cap and rotor off and checked it and it was fine... then i took the throttle body off and took the plugs out and they were fine and i checked the gap and they were all .043 so i put them to .04 and put it all back together and now it runs fine?????? so hopefully it was the plug gap or the thottle body had an air leak that i fixed when i took it apart and put it together again??? thanks Quote Link to comment Share on other sites More sharing options...
