just cured two niggling probs on my cx. thought mite be handy info for some owners.
1. overheating problem. caused by previous owner not fitting rubber mounting on bottom fixing lug on radiator correctly,made small hairline crack in rad. braised repair at local rad centre.
2. intermittent misfire at 4000 revs then seemed like fuel starvation further up rev range. ignigtion points nearly welded shut! but the car still started fine!
hope these help some owners.
