But when I come to stop light, the engine want to stall, I put in Neutral, I push gas so it keep that way, when it's green light, I push brake and accelerator in same time, I put Drive and I release the brake. So it go w/o stalling. But it jerks.
The engine misfire alsmost 90% of the time in this 10 miles (30 minutes) test drive.
I check the code, I got only the P0301 code and also the old classic 171/174 code which is normal for a Windstar 99-03.
So only cylinder 1 misfire???? Very strange.
So my question is: It's possible to make the engine run with only 4 or 5 cylinders, instead of repairing the valve? Well, I guess it's a valve problem.
So the engine will not stall anymore.
When I removed the plugs n° 1, there's oil deposit in it. So I guess, oil leaking through the valve to this cylinder, it's why it misfires.
So if I make the engine works with the plugs n°1 removed and connect the plugs wire to GND, so that current will flow to plugs 5, engine should work fine?
because I can't afford a valve or piston reparation, it's more than the car value.
I really feel like in 60s decade working with old combustion engine. Exept that I have automatic transmission. I wish I could have a clutch, it'll be easier to drive, instead of put N and D at each red light. It'll stop jerking.
