replace your car's engine with a chevy spark 800cc engine. and then add the frills to make it look like a racing car.

A honda tech will put it on the diag machine and solve the problem.















You might not like the outcome though, as this is unusual for a Honda engine.















I think your problem is the on board engine management system, all chips and so on.















Good luck.
