Whats Wrong?
Hi, I'm having some problems with my engine. I don't know if this is normal for every truck or not but when I'm tuning the engine this is what happens: When I set the HSN to run rich it does....but then when I start to drive it its like it leans itself out...Ill give it full throttle then ill stop (its running rich but thats alright) I do the same thing right after I stop full again then stop and so on...and after I do this about 4-6 times the engine is running so lean on the last time I give it full throttle its crazy. Then after I'm done doing that and I let it sit (running) I can do the whole process over. It starts out rich again and then becomes lean. Can someone help me out plz..Could this be an air leak or is it just normal...I know my buddies truck doesn't do that.
Thanks for the help guyz and gals
