Hello,
I need some help, I finally fixed all my vacuum leaks, the car idles fine, have a Hot Spark installed, and timing seems to be OK. Today I drove the car a bit and after a while the temp gauge indicated that the car is running hot, the needle moved over the P of TEMP before I decided to stop and take a break. After 30 minutes I started the car again and drive immediately home, needle again indicated that the car is running to hot. Before I fixed all vaccum leaks the car was running like ... but the temp stayed consistent in the middle, so I assume the gauge is fine. What to check, the knob on the ECU is already all the way to rich. - Juergen |

I'd double-check all the vacuum hoses for proper routing and connections first.
Are there two ports on the vacuum canister on your distributor? Are the advance and retard hoses plugged into the correct ports? I'd also try reinstalling a set of regular contact points in the distributor just to eliminate the 'Hot Spark' module as a possible cause, although changing to a solid-state point system shouldn't create overheating issues. Does the engine pre-detonate (ping) on hard acceleration? If so, try retarding the timing a few degrees. Another item you might check out is the pot (potentiometer) for the richness control. It could have gotten some debris in it and not providing the ECU the proper voltage level (think dirty volume control on an old 1970's era radio) (IMG:style_emoticons/default/idea.gif) Try turning it back and forth several times to see if it cleans up the wiper. |
