Can I get more HP out of my Safari Van

if thermostat is bad the computer will think the engine is still cold and will not let the timing advance witch will cause your problem also need to get check engine light problem taken care of before wasting money on cold air intake and etc mechanic for 43 years

@beaver, thanks

Catalytic converter is original. Were you getting a check eng. light?

I never did get a light. I bought a universal converter that bolted right in and it has ran like a top ever since. I have 320,000 on the truck now.

Check engine light code first before wasting time and money on something you don’t need

you said tune up you was going to do , make sure replace fuel filter at that time too
