I have a 1992 RS 3.1. The car acts as thought is has a timming problem. I checked the error code, code 33 came up . I replaced the MAP sensor but to no avail. The car starts fine bet when you accelerate it hesitates and misses. I changed the fuel filter, checked for vacume leak, had the fuel injectors cleaned and Emptyed the gass tank to make sure there was not some baf fuel. Amy suggestons

 

Change your plugs, wires. and at least check the distributer cap for corossion.

 

Just to let ya know. The knock sensor retards timing and creates a really bad hesitaion. Its located right above the starter mine had a broken pig tail and was off. When i started up and ran cold it ran fine then after a while it got a huge hesitation and stalled out at lights and idled ruffly around 600-500 rpms.

If broken the pig tail was $15
And the knock sensor is $35 non returnable

 

I had all ready change out the knock sensor and replaced the connector. It was causing my check engine light to come on. Thanks for responding

I have changed out the plugs and wires so I guess the next step is the distributer cap. Thanks
