Vehicle is 1994 Ranger, 3.0L, 2wd, 49 States emission, 131,000miles.
Failed California Smog at 15MPH on all gases(HC 172:CO.73:NO 1354.)Fine at all other tested speeds.
Diag from shop indicates Code 40(; I am unable to find this code.) Repair recommended is new cats(both) and reman engine install(low compression cylinders #4-100 and #5-130.)To correct rough idle. No recommend of fuel filter, injector clean, throttle body or MAF clean. My question is: what should be the cylinder compression reading and what is code 40?
Any questions, comments, or recommendations will be appreciated.
have the same problem?
