It has hard time starting when it is warm outside or when it has been driven for a while. I have replaced the maf and the intake manifold gasket and still no luck. I have p0171 code. When it first starts, it jumps to 2000 rpm then slowly go down. I tired to find a vacuum leak but cannot find one. At 700 rpm, the shrtft1 is at -20.3. Longft1 is at 30.5. O2b1s2 is at 0.115 and o2b1s1 is at 2.395. This is all from live data.
Freeze data at 900 rpm.
have the same problem?
