luvmytoys Posted November 14, 2007 Share Posted November 14, 2007 I am having some problems with hesitation at higher speeds. It just feels like it isn`t all the way loose and then it kind of hesitates...I have replaced the wires, plugs, fuel filter, air cleaner and even a new alternator. This is a 22 R engine carburated. Any ideas? Quote Link to comment Share on other sites More sharing options...
SanDiegoPaul Posted December 1, 2007 Share Posted December 1, 2007 your description 'doesnt' feel like it's all the way loose' does not make sense. Sounds like you are describing a misfire at part throttle...is that correct? Or is it worse at full throttle? Engine hot or cold? Did this condition exist before replacing the plugs and wires? When you replaced the plugs, did you gap them correctly, and what brand did you buy? Have you run a compression check on the engine? Check all the plug wires for continuity and resistance. I know, you said that they are new. That does not mean they are good. You should see about 1K ohms per foot on good plug wires - and be sure to check the coil wire as well. Speaking of the coil, if it is bad it can be breaking down under load and causing a misfire too. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Supurcar Posted December 2, 2007 Share Posted December 2, 2007 You need to determine if is fuel or spark causing this, usually hesitation to me suggests fuel. Maybe a bad fuel pump, maybe even a crack in a vacuum line. Any bad smell, maybe a plugged catalytic converter? Good luck. Quote Link to comment Share on other sites More sharing options...
WME Posted December 2, 2007 Share Posted December 2, 2007 The Toyata carb has an extra accelerator pump (AAP). Its common for it to leak this causes the engine to hesitate. Quote Link to comment Share on other sites More sharing options...
