Yea, I know I have one cracked coil for sure. But I've read on here that even with a lot of spark scatter it should run fine at lower boost and power levels. Its seems it only cause a real problem when people try to turn up the boost. I still think I have some kind of fuel line restriction...
I know it's not a China Walbro...I got it from a reputable source while I was working at a well known performance shop.
Today I put a new fuel filter and changed the oil and oil filter. It's still breaking up once the RPM's climb under load. I need to pull the inlet line to the fuel pump...
I agree with tissimo, I've had a hard top and targa now, and I'd rather have another hard top. It is nice driving with the top out, but not worth the hassle.
Yea, I was looking at a spare pickup I had and the lines are the same ID as all the braided steel hose I'm using, so that shouldn't be a problem. Now I'm thinking maybe the intake filter could be restricting the flow, but I'm not sure. It's the OEM in tank filter from the 1984 celica, which...
For the first time I feel like I made some forward progress today, if only a little. I can now get the car to go into boost at low RPMS while driving without it breaking up. I'm getting good fuel flow through the fuel filter to the motor. Looks to me like a good solid flow. If I'm in 3rd or...
Ok here is what I did today.
First, pulled fuel line off the inlet of the fuel filter at the engine. Brought that out the side of the car and hooked the pump to 12V and spurts of foamy gas eventually came out. Pulled the tank and found a leak at the top of the pickup filter tube...
When I dropped the tank yesterday and pulled the fuel pick-up the 6" hose inside the tank was deteriorating and swelling. I cleaned the filter then and put a new fuel hose inside the tank.
I'm about to go work on it now. Just thinking about it now, I wonder if the suction from the fuel pump...
I made some interesting discoveries last night trying to figure out my fuel problem. I went to a local shop yesterday to test my MAP but the Supra they had their couldn't be started.
I went home to try the pinch test, put some vice grips on and tightened them until the fuel pressure rose to...
I have not checked the ECU that I have in there now...but this is the second ECU I've run the car with. When I first got the car running it would lope a lot at idle, then at certain throttle positions. I put a known good ECU in and it stopped loping. I then bought another ECU and it doesn't...
That makes sense in itself, but doesn't explain why I had the exact problem with the stock 370s in.
I've replaced the vacuum hose to the MAP. Runs right to a port towards the back of the manifold. I don't have the budget now for an SAFC, I just want to get it running properly without...
