I recently purchased a 93 Del Sol with a swapped H22a4 and a H23 trans. The guy did it in his own way. The way where I have no idea what is going on under the hood. Especially with the fuel regulator it simply isn't there and nothing to attach it. That being said it sometimes hops while going excess mph I narrowed all the possibilities to that due to the car struggling to get fuel. So my question is what do I do in this situation? And what is possible cost of fixing the mistakes on faulty wiring etc.
