wadeblues Posted April 22, 2005 Share Posted April 22, 2005 I just bought this Paseo. The idle fluctuates when cold between 1200-2000 rpms. Once the car is warm, it seems to quiet down, but still idles between 1000 - 1200 rpms. It will also lurch when at a stoplight - more pronounced when the a/c is on, but still when not on. When cold, the idle sounds like it is gasping for air. It is a regular pattern (up, down, up, down, up, down). There is a (fakey) K+N air filter and enlarged exhaust, but I don't know if any other engine modifications were done. It is not a cold air intake, just a larger tube basically. Could this be causing the problem, the air intake or the exhaust, or both? If not, I have read maybe the battery connections, fuel filter, air intake leak, or vacuum problem. No problem on the first two, but I don't know how to check the latter two problems. Oh, also the brakes seem to be not grabbing well, and they were just serviced. Does this indicate a vacuum problem on this car? Can anyone help? Thanks, Wade Quote Link to comment Share on other sites More sharing options...
fidgits Posted April 23, 2005 Share Posted April 23, 2005 I would say it sounds like this induction/filter kit wasnt designed for your engine, and could be causing the problem.. although, it might be worth trying to reset the ECU first?

fidgits Posted April 26, 2005 Share Posted April 26, 2005 I thought I would reply on the forums, just incase anyone else has similar questions... To reset the ECU, best bet is to disconnect the battery, then leave a couple of minutes - press the brake pedal to get rid of any charge in the system, and that should have done it.

fidgits Posted April 26, 2005 Share Posted April 26, 2005 I don't know if this helps or not, but the speedometer reading is pulled up from an increase in rpms, and the brakes are very tempermental. Does this all indicate a vacuum problem? Wade What do you mean by the speedo statement? is that different. I would not say the brakes are related to the intake at all..
