CBLex Posted October 7, 2009 Share Posted October 7, 2009 Ive been having this ideling problem with my 90 Lex LS400. I started having the tale signs of needing a tune-up, so I replaced spark plugs & wires, new air filter, new fuel filter, dist caps & rotors, the whole works. Since then yes, the has gotten its powr back and all seemed ok. Now I still have this sputtering, mostly during a complete stop, car sputters, slightly vibrates like I just put in badass edelbrock cam lol. When I drive at times when I press down on the accel. the car hesitates giving it a little kick feel to it. I double checked all my work and everything is accordingly, MAF seems to be in good condition, and the airflow box above the valve cover passenger side(sorry dont know name of part) has been replaced, and ive recently put some Fuel Injector treatment. So aif/fuel delivery seems to be ok. Anything else I can check for? any help would be greatly appreciated! Chris Quote Link to comment Share on other sites More sharing options...
