92Lex Posted February 21, 2007 Share Posted February 21, 2007 Have you tested the TPS? Does the problem persist after the vehicle is warmed up? For the vents, have you checked the fuses? Quote Link to comment Share on other sites More sharing options...
blitz960 Posted February 22, 2007 Author Share Posted February 22, 2007 funny you asked if problem persist after the engine is warmed up... matter of fact, it goes away, after the engine warms up. the VSCOFF and CEL would still be on but the throttle feels ok after a while. in fact, these last few days, the weather in the morning had been around 50s (warmer) and those pesky lights dont even show up anymore. i'll try to get the TPS checked this weekend and i'll let you know. as far as the vents, now, sometimes it blows, sometimes it doesnt. what could caused that?.... thanks for the reply!!!!! ;) Quote Link to comment Share on other sites More sharing options...
92Lex Posted February 22, 2007 Share Posted February 22, 2007 Check and see if the wires (to the blower motor) are snug. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted February 22, 2007 Share Posted February 22, 2007 I would find out if you need a new battery causing the system to reset at start up . Quote Link to comment Share on other sites More sharing options...
blitz960 Posted February 22, 2007 Author Share Posted February 22, 2007 Hi, thanks for the prompt replies.... i'll definitely have the wires to the blower motor checked and as well as the battery. just curious, ... could the battery cause the system to reset and have the VSCOFF and CEL lights to come on and the car to react like that?......thanks!!!

lexusnutt Posted February 22, 2007 Share Posted February 22, 2007 The sticker on my fusebox says that in case of battery replacement, put the parking brake on FIRMLY, car in park, reconnect the terminals, start the car and wait up to 15 seconds. It worked for me. Quote Link to comment Share on other sites More sharing options...
oohryry Posted February 22, 2007 Share Posted February 22, 2007 Sounds like the connections are wired wrong to me. Might want to have that checked out to make sure everything is in the proper place. Quote Link to comment Share on other sites More sharing options...
