Hey guys! Hope someone out there can help me out. I'm having problems with my engine coughing ( missing ) and sputtering when accelerating and also on steady revs at about between 2000 and 3000 rpms. This causes the car to lose power and shutter. The problem is worst once car is warmed up. The car starts great without even having to step on the gas but idle sometimes becomes erratic. I adjusted the dwell, timming ( with strobe ) and idle ( idle as best i could ) but can't put my finger on the problem. I would appreciate any tips, info, or idea anyone might have. Cheers, Dominic.
p.s. I'm in the Canadian rockies, would elevation change specks car should be at?? |

QUOTE(Tab914 @ Aug 15 2004, 07:25 PM) Hey Nathan! This might sound stupid but what is the CHT? Also can you tell me how the ignition might have something to do with this? Thanks Nathan. I ain't Nathan, but if your high tension wires (in Canada, they are known as spark plug wires) are old, they can arc to ground or between each other. I used to wait until it go dark, fire the engine and rev it a couple of times to see if they were arcing. There is a better method with a VOM (volt-ohm meter). In the cap, the spark can arc to ground. This is easily seen inside the cap as black fine lines that look somewhat like lightening bolts. Or the contacts can be so worn/corroded that the spark doesn't jump from the rotor. Bad spark plugs etc etc etc on ignition. Other than that - Bad tracks in the TPS (throttle position sensor) Dying fuel pump - can't get up to operating pressure when warm CHT = cylinder head temperature sensor - near #4 cylinder in a hole thru the tin - a bitch to get at. Otherwise known as temp sensor #2 |
