ZXT Barn Runner Posted March 1, 2012 Share Posted March 1, 2012 Recently I purchased a barn find 82 280ZX Turbo with automatic and only 30000 miles. Car war running sound but 30 years unkept rubber in engine figured I'd have a full tune up done. 8.5 mm wires, new cap, rotor, NGK plugs, fuel filter, oil filter. Now when I drive it, car starts to lag when boost reads 0. In first and second can notice hesitation, but in third car bogs out sometimes misfiring. Can sometimes press accelorator to floor and power thru hitting full boost but ya still feel the bog. Checked all hoses and seem good know and vacuum leaks its over. Anyone have any ideas to what might cause this??? Hard to have a fun car when can't drive over 60 MPH.... Quote Link to comment Share on other sites More sharing options...
Juarez88 Posted March 1, 2012 Share Posted March 1, 2012 maybe your wastegate is stuck open? I'm having a similar issue too... Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted March 2, 2012 Share Posted March 2, 2012 Take off the driver's kick panel and gently wiggle the wires that go into the ecu. Often only takes a light touch. Quote Link to comment Share on other sites More sharing options...
FricFrac Posted March 2, 2012 Share Posted March 2, 2012 Check the AFM connector as well. CHTS is another important grief causing sensor. Get the FSM and measure your sensors to the ECU - simple resistance checks mostly. FSM is at www.xenons130.com Quote Link to comment Share on other sites More sharing options...
