I just replaced my 1.7 with a 73 2.0 that has been sitting for a few years. I got it up and running yesterday but it won't idle, maybe at 200rpm's. adjusting idle speed has little effect. The engine revs easily and comes back to idle quickly.
I have all matching FI components, no vacuum leaks that I can tell. double checked my vacuum hose routing per pelican's diagram ECU idle mixture is set between factory mark and full rich (doesn't seem to make any difference other than smelling more fuel out of the exhaust) Valves adjusted and timing set. Fuel pressure is just about 30psi. I am pulling about 20hg at 1000rpm. The only issue I have is some popping once every minute or so out of the exhaust when letting the engine run about 2500rpm for a while. |

Think so, but I have been wrong many time before...
I would first check the injector grounds....top bolt under the plenum. Second...get some glass baby food jars and put all four injectors in the jars...still hooked up to the car. Remove the high voltage main coil wire from the coil to the distributor. Turn it over (ideally have someone do this for you so you can watch) And then see how much fuel is in each jar... If you do all four at once...its easier to compare. Rich |
