When I boost for too long it cuts out. It bucks around like im on damn bull in a rodeo. First gear is ok no perfect but second gear its like uh fuck you. This is stupid another reason I told the guy 1000. I would say fuel cut but its all stock. I ran the codes. It gave me a 41 and a 34 with there isn't a 34 from what i can find. Please help I wanna boost.
Have you gone over all of the vaccum lines ? Do you have a boost/vaccum gauge ? Whats its read at idle ?
Yeah it has the stock boost guage. It reads nothing at idle and nothing a cruise. So it would be what -4. No I haven 't gone over anything because Im so overwhelmed with the whole fact that its a turbo engine
This should help straight from the 89 BGB. Code 34 System: Turbocharging Pressure Signal Diagnosis: When the fuel cut-off due to high turbocharging pressure is occurred. Trouble areas: Turbo, Turbocharing Pressure Sensor and related ckt, ECU. The Turbo pressure sensor. With the connector disconnected,Terminals E2 and VC with the ign on should be 4-6V on the harness connector I can scan out the pages for you if you need them. However it sounds to me like the wastgate isnt opening up. Check the wastegate actuator and the vacuum lines to it. Also, it idle and crusing you are always going to read vaccuum or a negative number. Its not until the turbo spools up are you going to get boost ie:when you punch the gas.
also make sure the damn thing is plugged in. should be on the firewall near the wiper motor. 3 wire map sensor with 1 vacuum line to the manifold.
I will check it out. But The boost is acting funny I think 1st gear ----2-5 2nd gear----Spike 8+ 3rd gear----Spike 8+ don't know about 4th and fifth because it decides to over heat when I boost and also buck like a bull.
***UPDATE*** I fixed my boost problem. I was getting that code 34 for turbo pressure. Well The bucking around was fuel cut. Because the hose that goes from the turbo to the wastegate was ripped in half. So I was running the maximum boost that poor little CT26 can put into that engine. So I was over boosting and getting fuel cut. Yay go me I fixed it.
