Engine floats back to idle
Hello All!
Both of my Opels are now running, Stealth is not ready but the Ascona is ready to drive. During my initial test of the engine and partial tune I noticed when you accelerate, the engine floats back slowly to idle on the last 400 rpms. I took appart the complete induction side of the equation and re-assembled it but found no problems. I also replaced the distributor but the problem did not go away.
The 1.9L has a ported intake with the torker mods and a 250Cfm Holley marine two barrel carb. All cylinders fire and the sparkplugs look OK after a short run. But the problem is there, you accelerate to 2500 Rpms and the engine comes rapidly back to about 1200 and then floats back down to 800 rpms. With the exception of this problem, the engine runs quite well though not fully tuned.
Has anyone had a similar problem?
