The pressure gauge is connected to the inlet mainfold and turbo bypassvalve, not the wastegate...... A leaky bypassvalve may cause these problems (not the check engine light). The easiest way to check the bypassvalve is to disconnect the hose on the inlet mainfold and then try to suck and blow into it. It should not be possible to blow into it. When you suck on it, put the tip of your tung to the hose: It should hold pressure. If not, there is a leak. Check hoses and valve. As Chris points out, check the dashpot (BGJ, there is no such device on '91 cars if Iam not misstaking), I believe the delay should be a couple of seconds. /Mathias BGJ wrote: > My 91 9000 did exactly the same.
