Hello Brickers.

An aquaintance of mine has a p1800 with early d-jet and under light load it surges pretty bad at a rate of a little over 1/sec. Has new vacuum hoses. New TPS. I haven't really checked anything because I'm no d-jet guru and its not my car. but i was wondering if anyone has any advice.

Thanks,
-Dana
 
check for all vacuum leaks: sealings between injectors and head, non return valve in carterventilation, Vacuum Injection regulator: should be air tight, cold start injector.
Check thermo-time switch at the back of block.
Good Luck !
