Welcome to the forums! Nice to have another Kiwi join up
. According to my Haynes manual, a code 42 would indicate a problem with the vehicle speed sensor. Diagnosis - No speed signal for 8-seconds when the engine speed is between 3,000 and 5,000 rpm and the transmission is in gear. Trouble area - Vehicle speed sensor or circuit, ECU, speedometer, or instrument panel printed circuit. I'd lean more towards the speed sensor or speedo being at fault as the 4A-GE ECUs don't have a tendency to cause problems.

. Yeah I'd try the speed sensor first. Typically if these go bad then you'll lose about 500-700rpm from your rev range, meaning you'll redline earlier than you should. I was thinking about it last night, and although there are two GT Apex Levins with 4A-GE 20v engines at Pick-A-Part Mangere, only one of them in a 5-speed. The other is an auto. The 5-speed one is right down the back, to the very far right of the Toyota section. So if you walk in, head to the Toyota section, but go as far as you can to the end on the right (as if you were walking towards the road you went down to get into Pick-A-Part. It's maroon in colour and you can't miss it. It's been there for at least a month, so you might want to get down there this weekend as they tend to remove the car from the yard after a month of sitting there. Good luck!
