mudfinder Posted March 28, 2005 Share Posted March 28, 2005 today at school, i was messing around on big dirt and asphalt piles. at crawling speed, almost to the top, my path started knocking and spuddering. first time it did that, any ideas what could cause that? :confused: Link to comment Share on other sites More sharing options...

mudfinder Posted March 28, 2005 Author Share Posted March 28, 2005 (edited) i've changed everything, i mean everything. from fuel to air. i had two mechanics test my injectors and the injectors are working good. i'm just worried it's my tranny. i want to fix my manifolds before i do anything major. btw, i had a 1/2 tank of fuel. when ever my check engine light comes on, it always give me code 13(engine coolent temp. sensor). and gave me 45(injector leak) once. like said eariler, i had it presure tested for leaks, and their working fine.

Cuong Nguyen Posted March 29, 2005 Share Posted March 29, 2005 I can't see how your tranny would cause sputtering and knocking. Do you have any problems driving it around? Link to comment Share on other sites More sharing options...
94extreme Posted March 29, 2005 Share Posted March 29, 2005 when ever my check engine light comes on, it always give me code 13(engine coolent temp. sensor). maybe you need to burp it... air bubble in the system might throw out 13... Link to comment Share on other sites More sharing options...
mudfinder Posted March 29, 2005 Author Share Posted March 29, 2005 when i punch it off the line, it barely moves. the rpm goes up and down, up and down. i said tranny because when climbing the hill it left more a drive train issue rather than the engine. how would i burp it? how would i get the bubble out?

NissanPerson Posted March 29, 2005 Share Posted March 29, 2005 The water temp sensor will do crazy stuff like that. I was having problems with sputtering, dying, dropping to idle under acceleration...hasn't done it in a while but I changed EVERYTHING too. Talked to a mechanic friend and he said he'd check the water temp sensor off the top of his head. So, I replaced it and my car still did weird things...but I'd give that a try ESPECIALLY since you're getting the code showing up. Now when I drive mine when the tranny shifts it feels like the thing just BOGS down like mad. Engine revs up but when it shifts to the next gear I swear it's going to sputter and die. Can a tranny somehow kill an engine by bogging it down? I'm sure it could but has anybody ever had/heard of that problem? Link to comment Share on other sites More sharing options...

I'm sure it could but has anybody ever had/heard of that problem? only if the shift celenoid (AT) goes bad and i don't know if pathys have one...

94extreme Posted March 30, 2005 Share Posted March 30, 2005 how would i burp it? how would i get the bubble out? on pre 90s there is a little screw/bolt in the upper rad hose that you loosen. the air shouldcome out and then when antifreeze starts to flow you turn it back in.. this is all with the engine running and heat on HI... on my 94 i didn't see that screw so i'd do the old school method and take the rad cap off, let the truck run and warm up (heat on HIi) and top off the rad till it couldn't take anymore...letting the fluid circulate at least a couple of times... for both: then you add antifreeze to the recommended level in the reservoir and you should be good to go...
