It was the battle of the two Matt Taylors at St.James Park as both were made to settle for a point as two goals from either side either side of the break meant that the spoils were shared.
The Saddlers were backed by 370 fans on a wet afternoon down south and it only took the home side five minutes to take the lead as a cross from the right came into the box and found Dieng at the back post who towered high and powered a header in off the post with Carl Rushworth left stranded.
But that was the only chance of note that the home side had in the first half as the Saddlers then took it upon themselves to take the game to the Grecians.
After 21 minutes, Miller had a great chance to level the scores as he beat his man leaving himself in a one-v-one situation with the Exeter goalkeeper but his left-footed effort went wide of the far post.
Moment after that chance, Miller again went close from just inside the area. Kieran Phillips picked the ball up on the right-hand side and delivered a pinpoint cross into the box for Miller but his header was just wide of the target again.
Miller though finally got himself on the scoresheet as Brendan Kiernan was tripped in the box and the on-loan striker stepped up to smash past Cameron Dawson in goal.
Into the second half and the home side had a great opportunity to get themselves back ahead as Dieng was fouled inside the area but top goal scorer Matt Jay saw his penalty saved onto the bar by Rushworth.
Just after the hour mark and the home side did regain the lead through in-form striker Sam Nombe. He got round defender Rollin Menayese and slotted the ball past Rushworth in the Saddlers goal.
But just moments after that, the Saddlers were level again, with Miller grabbing his second goal of the game. A fantastic cross from the right from Hayden White was met by an unmarked Miller and his header zipped off the surface and into the far corner.
Nombe had the best chance of the closing stages as he once again got beyond Menayese but his effort could only find the side netting and that missed chance meant that both sides shared the points on the day in Devon.
