1988 Volvo 740 GLE SW B230F backfiring

1988 Volvo 740 GLE SW B230F
Approaching 200,000 miles - engine seems to be running rich - backfires between shifts - smells pretty bad!
I haven't tuned it up for 7 years other than new spark plug wires......guess I just partly answered my own question.......but......my question to you is: where's the best first place to start - given I'm on an artist's budget and don't mind getting my hands dirty.

1988 buick Century backfires so hard it blows the muffler apart?


A backfire in the exhaust system is usually the result of a rich mixture ( too much fuel ) being supplied to the engine. It can also be a result of a timing/ignition problem. Does the vehicle run ok at idle? Is the check engine light on? If so, have the codes scanned for any problem areas that may be causing a rich mixture

I have a 88 volvo 740 GLE and it wont fire.


The problem wont be your timing belt. you need to take out a spark plug plug it into your HT lead and check for a strong spark or even if there is a spark. check your contact breakers on the distributor as well
