have the same year 2 door. have you checked your iac? if you get a repair manual you can check alot of the sensors with a volt meter. its pretty self explanitory in the book. you could of easily changed the injectors yourself if you did the tune up and fuel pump. get a book and look into how...
when it gets to normal operating temperature it idles normally so I dont think it's a vacuum problem. changed the iac and didnt make a difference. will try changing the tps later today.
ok so my 95 is a work in progress lol. finally believe I got the vacuum leak fixed properly or as close as its gonna get (but it works). had to use an elbow off another make vehicle on the backside of the tbi that goes to the valve cover, basically a ventilation hook up. shifts alot smoother...
no problem. had to look at it again. mine would only work on high when I got it, researched and found that the resistor would do that and the relay controls high. remembered the wiring thing after a second too. mines a 95 ls
possibly relay, thats what controls the "high" speed. otherwise theres a connection thats known for this problem in late 70s to 90s gm vehicles. found this...
Start at the blower motor. Its wires will be purple and black. The blcak one goes to the chassis; the purple one goes to the relay...
bad resistor usually will make the blower motor work on high only since it basically tones down the voltage to make it run at lower speeds. thats maybe not actually how it works but you get the idea lol.
what year is it? might help to know
still showed running rich at normal operating temp when I got it inspected but really bad judging by the smell at start up. hadnt done a compression test. new cap, rotor,plugs and wires
yes replaced the cts. it smells really rich at initial start and the emissions report , which it passed, but still showed running rich. new y pipe with cat and o2 sensor. all vacuum lines are hooked up.
95 tahoe tbi. have replaced everything except the tps, map sensor and throttle body itself, full tune up. still runs rich especially before warm up. one thing Ive noticed is if it sits for a few days the tb hangs up as if the butterflies catch on something. its not in the cable its in the tb...
not sure what year yours is. mine is a 95 and I have read the brake light switch has 2 relays or whatever you want to call it. one controls the lights in the tail lights and the other controls the third light. my third brake light is stuck on and the brake lights in the tail lights work...
