I'll check that.A couple of things to look at, the oxygen sensor, knock sensor and engine temp sensor harness runs up the front of the engine. If routed wrong it can cook on the exhaust manifold.
Not sure if i understand correct. Vacum for map sensor is on the manifold. I have a renix, 1990. Not sure how it's done in newer models.Two holes in the throttle body for the MAP sensor vacuum line. Only one home goes all the way through to vacuum.
I checked that, its ok.The vacuum tube for the MAP is prone to rub through or crack, it only takes a tiny flaw to cause issues.
Ill check, but i did not have any problems with setting a correct position of TPS.Do an ohm test on the TPS ground. That ground circuit has many splices any of which can cause issues.
I'll try but i see no point. As i said before i have an LPG system and it's the same on LPG and on gasoline.Jump the ballast resistor.
I checked most of them, and as i said before i have duel fuel system, and the LPG ECU shows your vaccum pressure in real time so i can see them map of it and i know if i have a problem with vaccum or not.Didn't see it mentioned( unless is missed it), but you might check ALL your vacuum lines after checking the MAP line.
It's disconnected and vaccum lines are 'sealed'. No vaccum leak.I know egr was mentioned but is it disconnected or blocked off?
Yes, it works, fuel pump is new, and problem is the same on both types of fuel.Have you verified fuel ballast is functioning and fuel pump is good?
I'll leave it to the smarter mechanics to discuss your timing.
If the EGR valve is stuck partially open, which I've seen before, it won't matter if the vacuum lines are plugged. It could be introducing exhaust gasses into the engine when it shouldn't. If you have a drill and a flat piece of metal, make a quick block off plate and give it a shot. Can't hurt to rule that out too.szachmat said:It's disconnected and vaccum lines are 'sealed'.
