So the ECU didnt fix the problem.
I've replaced the ECU, knock sensor,
coil pack and I think something else
so far. I have a spare crank and cam
sensor I'm gonna throw on tonight.
I think I may have fried some wiring.
Ok, so I copied this from another forum.
Here's the scenario:
About two months ago I did an engine swap. This engine sounded great, ran great and not a bit of smoke or oil leaks so I bought it and took it home. I pulled off the valve covers and oil pan and sprayed the whole thing out with a gas/air mixture. I put on a new front main seal, rear main seal and cam seals. It got a new water pump, thermostat, timing belt, idler pulleys and valve cover gaskets. I ran some BG44k through it after it fired up to clean out any excess carbon and the engine was running awesome! I installed a manual oil pressure gauge to keep an eye on it since it was a new engine.
Well the other week the oil pressure gauge piping started to have a small leak due to having to move it once and reuse the compression fitting. I ended up trying to use black RTV around it to prevent it from leaking and that didnt work. It had kicked on the oil light, but I was watching the psi and it read fine and the oil light went back off. Well it happened again so I thought about buying new piping. One day it was on for about 30 seconds so I shut the car off and it went away. I ended up going up and buying new piping for it that day and when I went to change it out the new piping was crimped. Well I took that back and got another. It was crimped too so I just bought an entire new gauge. I installed the gauge yesterday. When I went to install it I had taken the alternator off and before I set it down I noticed I had forgot to disconnect the wiring on top or on the battery. It had been a long day with little sleep the night before so I started to take it off and I dropped the alternator on the radiator support and blew out the fusibile link. So I ended up making a new one with new fusible link wiring from autozone and it ran perfectly yesterday.
So today it had been running awesome all morning and I went to my girlfriend's house. Well it was time for church so we left. Now I know it's an old car that I just recently swapped the engine on so I got up to 40 and I sped up pretty slowly up to 50 when the sign changed speeds and the car started to feel a little laggy and went away so I drove a bit further to see if it'd do it again and four seconds later it started to feel laggy again so I start to slow down to pull over and the engine shut off while I was driving. I put it in neutral and coasted to a stop without power steering or braking. I shut the car down and looked under the alternator and found oil coming out of the gauge piping. I started the car back up and it was running rough as I was watching the oil pressure through the gauge (didnt get to see the RPM's) and it was shaking...feeling like it was missing or something so I shut it back off after about 5 seconds. I ended up putting the old oil plug back on there and connected the line again and started it up and it sounded find. Ran smooth. Idled smooth. I drove it back home about 10 miles to my parents house and it drove perfect the whole time. I watched the temp gauge the whole drive didnt move after it got up to running temperature. I checked the oil and no milk and I checked the coolant and no oil. All of the fluids on the car are at the proper level and everything to my knowledge is plugged in.
Could it have been the leak in the gauge piping? Not having that sensor hooked up?
Anyone have this happen before or have any ideas?
