Subject: Re: Rough start/Sometimes rough idle by Fredbird on 2011/7/6 23:13:20 Well, at this point I've replaced plugs, wires, inspected Dis cap for cracks, tested the ignition coil, had the ICM tested and it was good. Checked timing, it's at 6 TDC, Replaced in-line fuel filter. I've not tested the Pickup Coil, but from what I understand that's a all or nothing part... (It will either start or not.) I know I need to replace the EGR Valve... I don't think this would cause this problem would it? I could see it causing rough idle, but not a hard start. Next to check, 1. IAC Valve - Clean and inspect... if good put back or replace. 2. Re-check spark plugs to be sure none are loose 3. Compression test - Should be somewhere around 170-180? 4. O2 Sensors - check for carbon buildup. Check with multimeter - No voltage when cold. Heat them up and I should start to see voltage. 5. Coolant Temp. Sensor - I read to test this by taking an ohm reading while cold, let the temp of engine to up then test again. If Ohms are lower, then the sensor is good. 6. Injector Ohm Test (I understand I should see 14 ohms or less... Correct?) 7. Injector listening test (I should hear a consistent ticking noise...) 8. Clean Intake manifold (This winter) Am I missing anything? |
