so i had a 97 cherokee sport about a year n a half ago and i blew a headgasket...so $1500 to fix it and i didnt have it so i just went a bought a used car, so that used car just locked up on me last week and i junked it...i found a street mechanic to do the gasket for me for $200 so he finished yesterday...the jeep took about an hour straight to start up(after a year n a half of not running) but now it starts but it shakes VERY badly...im scared to drive it...maybe a clogged injector from all the old stuff pushing out???? any help would be appreciated, thanks!

 

bad fuel,
check the firing order, spark plug wires put on wrong? crossed wires.
check those spark plugs as well, remove and inspect them.

 

id try and put some of that stabil dry gas stuff in

 

Can you describe the symptoms better? Shaking? Like is the engine shaking around inside the engine bay at idle?

Bad motor mounts maybe?

 

its old/bad gas. you cant just let a car sit for a year straight without prepping it first.

OP- run some injector cleaner or seafoam in it and put 5-10 gallons of 92 (premium) in it. This may be enough to loosen some of the gelled fuel up if you are lucky. On an explorer I had I ended up having to replace the fuel pump and all the injectors to get it to run right again after sitting.

good luck.
