Hello i just acquired a 90 gtu about 2 weeks ago that runs and drives mint. It starts up one time every time and only has 84k original miles. One problem i noticed with the car though is that after about 8 to 10 mins of driving the check engine light comes on and the car then begins to bog. i then turn the car off for about 5 seconds turn it back on and it drives like new. idk what the problem may be but i think it could be the mass air flow? weird problem idk what it can be please help.

 

It's probably a failed metering oil pump (MOP/OMP), which leads to limp mode. http://www.johnr.com/cpucodes.html
