Subaru Problems? Ask a Mechanic for Answers ASAP
Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be be posting a replay ASAP
is there a check engine light on now ? does the check engine light flashes going up hill when the it is shacking that way go up hill ( under load ) ?
is this engine problem i m assuming ?
is there any prior worked that could contributed to this issue or it suddenly started ?
is this something you looking to fix yourself and do you have test light, fuel pressure tester , scanner etc ...
does it only do it going up hill or when car is under load ?
does drive normal in straight away ?
Please let me know
