Re: 87 running lean?
check your tps voltage your readings showed idle voltage do it directly at the tps(with the engine off key on) with a voltmeter set to direct current between the black & blue wire should read below 1 volt at idle and slowley depress the throttle the volts should slowley increase to around 4.99 volts. can be as low as 4.00 volts as long as there is no dead spots in the reading ( a o reading or low voltage)
