1975 1.8L Ljet injection. Car is hard to start. It takes 3-4 tries and some time a shot of starting fluid. Fuel pressure gauge reads 30 lbs. in engine compartment. The rpm rises to 1800 rpm for about 15 seconds, then the idle hunts between 500 rpm and almost stalling out. After the engine warms up it runs and starts as normal. Vacuum hoses are tight. Comments?

Thanks everyone for taking the time to post replies. I replaced the O ring on the oil filler cap, found a slight vacuum leak. Then I removed the Idle adjustment screw on the throttle body and sprayed some brake clean inside as Tim suggested. I tightened the intake manifold bolts, and it started right up! Adjusted the idle. The idle holds steady and fuel pressure is 30 lbs. Chasing vacuum leaks will drive you nuts! (IMG:style_emoticons/default/wacko.gif)
