100nx 1993 runs very rough when gets warm ie no choke

[Ian Retro]

The car runs poorly once choke cuts off and stalls at low revs. When re started black smoke from tail pipe. Advised possibly throttle body or MAF sensor or lambda sensor. Changed both sensors as no Throttle bodies available with little progress. I don’t have access to Consult 1 so looking for thoughts on next steps!

Thanks

Hi Ian

Did you manage to find out what the cause is?

Have you also checked for air leaks on the inlet side of the engine (split hoses, etc)
