Hello Everyone.
I have a 1998 Lexus GS 300 w/ 191,000.
I don't know how to exactly describe the problem but here goes.
Check engine light is one w/ p1071 code - too lean condition.
The car idles fine. No stalling. No issues.
The car revs fine w/o issue in park.
When I accelerate, I can accelerate normally as long as I go SLOW.
If I give a lot of gas the car revs for a few seconds, you can hear a POOF sound come from the engine and then it eventually accelerates fast like it's supposed to.
I just changed out spark plugs and changed Valve cover gaskets but this problem existed before that. When I change the spark plugs out, I found them drowned in motor oil. When looking into the holes from where the spark plugs go, a lot of "crud" can be seen.
Anyone have a suggestion or can explain the POOF Sound ??
Much appreciated !
