Missfire

2000 Mazda 323 1.3 5Dr 125000 Miles
Car: Mazda 323
Year: 2000
Variant: 1.3 5Dr 125000 Miles
The Car starts and drives fine from cold. When the Car is warmed up if you are either taking off from a junction or going uphill i.e. anytime the Car is under a little pressure there is a noticeable Missfire. I presume it is a Sensor issue but which Sensor and where is it located exactly. As always many thanks for your help.

Not sure what is fitted to that year and engine but would have thought it was more likely to be a plug lead or pencil coil breaking down under load .Also suggest carefully cleaning MAFsensor .

Sorted - The issue was the following;

A new set of Plug Leads were put on the Car recently. The Sleeves that fit over the Plugs were too long and the contact was not fitting correctly on the top of the Plugs. Circa 2cm was cut off of the Sleeves, the contacts are now sitting properly on the Plugs and the Car is running as it should.

Thanks for the assistance again.
