My fellow nairaland auto experts I will need your candid and productive ideas on this problem.
I have a 96 Camry 'Orobo' the car works fine but since abt 2 months now the engine has developed a strange performance. However, the engine does not give me a good performance with AC on, that is whenever I use AC for say 30mins and turns the engine and is allowed to cool very well "especially when I return from work and allows it till nxt day" at next start the performance becomes very low and even goes off some times and I'll have to raise and allow it to warm for a long time before it picks up. Due to this I have been driving without AC to sustain its performance. Though I have been to my mechanic he's suggesting its the vacuum but not sure and could not put in any productive effort to stop this problem.

Nairaland people what could be the problem and way forward. Please, only positive responses are welcome, Oga Sienna where are thou?
