1986 Corvette code 33 and limp mode
On my 1986 Corvette it drives fine, but as soon as I hit a certain spot on the pedal right near where you first start pressing it, it sets Code 33 and goes into limp mode. If you stay just below that spot it drives fine, and if you go past it really fast you can still drive fine, but if you hold it there for more than a second it sets the code every time. If I turn the car off for about 15 seconds and turn it back on, the code goes away and it drives fine again until I hit that spot. I’ve already replaced the TPS and the mass air flow sensor and it’s relays but it still doing it. Has anybody had this problem?
