Ok, now I got a 89 2.5 turbo sundance. Only 2 problems so far:

#1. When cold starting, it starts nicely and runs fine for abour 10 seconds. Then, it sputters and misfires for about 30 seconds. If I hold the throttle at 2000 rpm, it will stay running but I can still feel it misfiring. If I don't hold the throttle it will stall out. Then, it runs fine again with no problems. Whats up?

#2. Boost gauge only goes to 0 boost. Assuming the turbo is good, is it possible that the engine is shot and boost is getting pushed out somewhere? (it runs fine just feels like a honda above 3000 rpms) Or, is the only possibility that the turbo is blown?
