Can someone help me please?
I changed the water pump on my ’83 X1/9 yesterday. The jobwent as expected; cut knuckles and lots of swearing as usual.
I took the car for a pleasant drive over the mountain roadsto enjoy the seldom-seen sunshine. Everything was fine for about 30 miles whensuddenly the car developed a misfire. The temperature gauge was readingperfectly normal, and the car had not lost any water.
Driving the car home it began to misfire very badly. Theengine cut out twice in heavy traffic and struggled to start. Almost as soon asthe misfire started it cleared up.
I have checked the plugs, and I have changed the plugs, butthe misfire is still evident. I have changed the HT leads, but the engine stillmisfires. A friend has used a compression tester and everything appears to befine. I have checked the leads to the Lumenition electronic ignition andeverything is fine. I can’t see any leads hanging off. The engine isn’t losingany water; it starts fine; and it doesn’t feel down on power; yet it still hasthis misfire.
I have got a spare coil; but I have mislaid it. Could theproblem be down to the coil?
I hope it’s not the head gasket?
Thanks.
