First you need a timing light which I assume you have. There is a notch on crank pulley,put a dab of white paint on it. Connect timing light, if off loosen bolt for distributor and adjust accordingly.Manual states 8 degrees BTDC @ 800 RPM. This is also assuming that all other components are in good working condition,timing belt etc.
The 89 is an s5 and the 87 is an s4 It will fit but might take minor modification.

The timing on a 1989 Dodge truck should be set to 10* after unplugging the temperature sensor.
where are timing marks on 89 ford probe 4 cylinder I have the bottom not the top
check timing. timing advance. or slack in timing chain/belt
10 deg BTD, tranny in neutral, spout connecter disconnected
I'm not sure about yours but we used to set them, bottom one straight up and top one straight down.
I have an 87 7mge non turbo and i beat my buddies 89 rx7 with a 13b and webber side drafts
89 Buick Century uses a timing Chain. Not a belt.
No. 86-88 are the same. 89-91 are the same.
i have a 93 4.3 tbi..i set mine at 13deg. works well on 89 octane. 12deg for 87octane at 700rpm
sounds like a sparkplug is fouled or the timing is off
