Hello. Need your advice on Injection Timing. My pickup (4ja1 with 73K in the odo) is running a bit rough when idling. Rough, meaning noisy as compared to other fuego pickups. This is specially true when I am using AC while the pickup is idling. I just had my Injection Nozzles cleaned. I also recently replaced the air filter, fuel filter, oil filter, all fan belts, and oil. But still the idle is still rough.
Nabasa ko sa isang discussion na "if you want your 4ja1 engine to be running smooth...as in smooth idling..you should have ur injection timing be corrected." Do you think an injection timing adjustment will help? Is there a recommended setting or frequency for the adjustment of 4ja1 injection?
Thanks.

Sa Mitsu kasi kapag medyo maingay, inaadjust lang yung valve clearance (yung sa tappets ba yun?). Ok naman na afterwards and its a relatively simple procedure. Baka pwede din sa Isuzu yun.

Open lang valve cover. Gamit feeler gauge (yung parang mga thin strips of metal). Adjust yung clearance by tightening or loosening bolts.
Di ko pa ginagawa sa Pajero ko. Sa Benz pinapagawa ko kasi minsan malakas yung 'clatter' lalo na kapag idle. Pwedeng gawin dun sa Motorcraft iyan siguro. Pa-adjust ng tappet ang tawag.

Sir Otep, salamat sa suggestion. Pa adjust ko ang valve-clearance ng pickup ko to smoothen the idling.
I also noticed that when the AC compressor runs, malakas na ang engine vibration kapag naka idle. (Kahit bagong palit ang engine support ko). Nabasa ko sa isang thread dito na baka may problem na ang idler pulley or the tensioner bearing ng compressor. Pa-check ko rin ito tapos i-post ko ang results. Salamat ulit.

yup...valve clearance lang siguro yan sir...if your fuel pump has not been serviced yet, most likely original setting pa iyan...that's what happened to me, pero 4jb1 naman...dati naka advance but then after ipa calibrate, back to original setting ulit yung timing and then umingay, had the valve clearance adjusted and now its running smoothly again...=)
