hello everyone I hope to find any help here


my car started to show a delay in startup but I noticed that this delay is absent in the early morning it turns just from single shot


to start the engine I must press the gas pedal when I do this a black smoke come from the tailpipe and It come in shots pattern not steady


all of these disappear after 15 to 20 seconds when the engine reach a fait temperature




I did the following :


changed the coils . HT leads and plugs ( when I instal the new plug and run the engine for just 5 seconds I found that the new plug became black - stained with carbon)


changed the O2 sensor
checked the ECT sensor and it work fine
changed the injectors and fuel filter and air filter
changed the engine oil and refilled the fuel tank




don't know what else I should do - I spent a lot of money and don't know what to do - the problem became less than before after all these changes but still there


thank you

have you noticed increase in fuel or oil consumption? if not, i wouldnt worry to much about that smoke
