I have a 2000 Civic Si (B16A2). I had an Edelbrock turbo added about 7 months ago. It only ran good for about a month. But now, it jerks a lot when my speed idles at a certain speed (for example - going 55 mph in 5th gear for about ten seconds). It only drives good when I am accelerating to a higher speed. This morning my car completely cut off while approaching a stop sign, but it cranked right up. Sometimes, the car will not even accelerate when I am pushing the gas pedal (it's like it bogs down). I have to put it in neutral, then rev it to about 5,000 RPMs and then put it in gear to go. It's really weird. Another problem that comes and goes is that my car is sooooo slow when accelerating from a complete stop. It will only go 5 to 10 mph for about 5 or so seconds. If I am going uphill, it almost will not make it. People always swerve around me wondering why a suped up car is driving like a grandma. It may do it one day, and then the next, it drives fine. Normally, my car runs great on the way to work, but I have to pray to make it home everyday. That's when I have the most problems. Anyway, the guys who put it on checked the timing and the wires for the ECU and piggy back, but they said nothing is wrong with that. They said I should try a new map sensor (but they can't guarantee it will work). They said it could also be my ECU going out. Does anyone have any idea what it could be? All answers would be greatly appreciated. Oh, also I have been emailing a technician at Edelbrock. I sent him pictures of the ECU and piggy back; he said it was fine. The only thing he could come up with is that I need my O2 sensors replaced to take the car out of "home limp mode."?? (the engine check light is on). Please help!!! And some more background info is that I had a burnt valve back in November 06. Since the engine was going to have to be rebuilt anyway, I decided to add the turbo. So, low compression pistons and Skunk 2 valves were added. Also, they put on a new Spec 2 clutch. (hope this info helps). They ran a dianostics on it last week and they said the only thing it shows is that the O2 sensors need to be replaced. I think I will take it to O'reilly or Advance Auto Parts and see if they say the same thing. I will get the actual codes and post them tomorrow. Btw, here is the list of parts that were put on my car in November when the engine was rebuilt with a turbo: -ring set -main bearings -washer st -rod bearing set -valve gasket -cam seal -crank seal -rear main seal -thermostat -drive belt -drive belt -Spec stage II clutch -drive belt -Skunk II valves -head gasket -oil and coolant -drive axles -Edelbrock turbo kit -piston kit turbo (set of 4) -turbo timer (I can't find page 2 of my receipt...there were a few more things). I will get it and post them as well.
