Try this first. Measure static resistance from valve cover to battery's negative terminal. Set DVM to ohms (DC). I have 0.2 ohm across the cover to the battery. The engine is running fine. You can try moving wires between head and firewall to see if you have a loose connection (ohm readings jump around as you move wires).


Good luck!

I had that issue with a faulty map sensor before. Wouldn't throw a code but the car ran in limp mode. Replaced sensor and never had the issue again

I had a very similar issue with my car, a quick sensor change and problem fixed..

I think i will change map sensor since it has been on the car for more 11 years

I wouldn't change until car goes back into limp. You might have fixed the issue by smacking it.
