Im having a major problem with my 93 240 and early morning cold starting. It cranks,but no sign of life. When its about 13-14c,then starts without a problem. Im wondering if its the coolant temp sensor for the computer. Is it possible the coil is effected by the cold? Looks like the original one. All leads replaced with rotor and cap and spark plugs.Other people have been baffled by this..and im ready to pour a gallon of petrol over her after sorting out other electrical problems.
Thanks for any feedback.
To answer my own question...i looked at getting a knock sensor from swedish parts and they mentioned low octane as a possible cause. So i switched to 94 E10 and 80% of the pinging is gone. But its still there. And it doesnt have the same get up and go as it does on the unleaded.I dont want to keep using E10 because its hard on the donk and cat. But the fact that its still pings shows something is still not right. Like the knock sensor. At least the pinging is not as bad. i was getting worried it would chew a bit out of the top of the pistons.
I am seriously considering putting water injection on this or my next 240 wagon. With a mix of 50/50 alc(metho) and water,it boosts octane to equivalent of over 110 oct. Im trying to find a youtube video of this and shown on a stock car put on a dyno. No mods,just water injection with 50/50 in the injected mix. He got the equivalent extra power of over 110 octane. Think it was actually 116. Been a while since i watched it.
Why not go E85? Doesn't hurt anything. Some on here have the injectors for sale to give more flow.
E85 is a lot more simple.
what would be the economy like on E85? All other 240 run fine on unleaded,so im guessing its the knock sensor.
The lower price for E85 makes up for any extra fuel used AFAIK.
Yep, cost works out the same until you boost lots and lots and bigger turbo and this dump in bulk fuel.
Boost lot and lots ...
Just wondering why a stock na 240 would knock om 91. Also never read about ethonal hurting the block. And cat? Probably not much left after all these years.
E85 is not the solution nor is meth injection for a stock car. Check the fuel pump and filter and regulator first...
