A late strike from David Clarkson rescued Bristol City and denied Coventry their first Coca-Cola Championship victory in their last five games.
David Bell's first Championship goal of the season just after half-time looked to have given the Sky Blues a fortunate victory.
But substitute Clarkson fired home eight minutes from time to salvage a 1-1 draw for the Robins, who missed a hatful of chances to secure all three points.
The home side had the better of the opening exchanges and on-loan striker Patrick Agyemang tried his luck from long range but failed to test Keiren Westwood.
James McPake had the Sky Blues' first strike at goal but Dean Gerken was never going to be troubled by the full-back's 25-yard drive.
Highly-rated Coventry goalkeeper Westwood had to be alert to keep out Jamie McAllister's left-foot strike with his feet after 31 minutes as the home side pressed for the opening goal.
Marvin Elliott had a chance to put Gary Johnson's side in front just before half-time but he failed to get enough power on his shot and Westwood made the save.
Clinton Morrison was off target with a 25-yard drive moments later but the first half always seemed destined to finish goalless.
But the deadlock was broken just a minute into the second half and it was the visitors who struck first.
The Robins failed to clear their lines after a scramble in the penalty area and Bell lashed home with his right foot from the edge of the area.
To make matters worse the home side lost leading scorer Nicky Maynard to injury five minutes into the second half.
But they could have been level 11 minutes into the second half when the ball fell to Agyemang on the edge of the area and the big striker fired over the bar.
Danny Haynes also fired wide as Bristol City piled on the pressure, but Freddy Eastwood should have done better at the other end when he fluffed his shot from 20 yards out.
Defender Lewin Nyatanga spurned another chance to restore parity but the Wales international headed wide from just six yards out.
Haynes missed two more chances as the Robins piled the pressure on Coventry and Agyemang failed to beat Westwood once with a tame finish from the edge of the penalty area.
And Elliott was also off target with a left-foot strike when he met Paul Hartley's corner 18 minutes from time.
But just as it looked as though it was going to be one of those days for the home side they equalised eight minutes from time with Louis Carey heading on for Clarkson to despatch a right-foot finish into the back of the net eight minutes from time.
