Hello, thank you for writing in. You are in a position where you need to do some further testing. You may want to start with the ignition system, and check the distributor and cables. You may also want to test your fuel injectors, and/or test your fuel pressure. If these systems pass their tests, you will want to check the EGR valve. With the other recent work that has been done, verify the new components are working and that the repairs are holding. For more help with further testing and resolving the issue, contact our service department to schedule an appointment.
