Hi there,

With this sort of problem you should stat with the basics, do a comp test and a full tune check that the timing is correct and check for any vacuum leaks, do a scan as well as some problems will not set the engine check light, it may be a good idea to have an on car injector service done as well as this will show up any faulty injectors.
