# 5 injector is miss firing is there a injector cleaner i can use the van runs a little rough

I wonder how they know it is an injector and not a plug or ignition problem ?
Yes Seafoam is a good product as well as other cleaners. If the injector is faulty cleaning will not solve the problem.

No codes will not start Engine cracks OK. 60 lb. fuel pressure. Has spark. This problem started after I replaced the transmisson.

i would check for any LOOSE OR MISSING GROUND WIRES that were originally bolted to either the bellhousing/starter bolts or if the wiring harness that runs over the tranny and connects to tranny switches has been cut/damaged. you would be suprised how many problems can occur because of bad/ missing grounds!!

1998 chrysler sebring convertable limited misfire on all cylinder

Assuming a "complete" tune up is plugs and wires. Recheck all wires that they click into fit. I would put fuel additive in the gas tank, I prefer to use the $3.00 method as opposed to the $65.00 cleaning method. You may need to do this more than once, but most deposits can be cleaned from the injectors by just running the additives. I'll bet you a quarter she 'purring' again in 3 days. Yes I've got the quarter. Sheesh!

Misfires, sticking 2-3 selonoid in tranny, and sluggish to start

I would make sure the engine is properly tuned. The miss fire condition could be making the transmission run poorly. Once the miss fire is repaired , then recheck the transmission.

The miss fire can be caused by several things after the tune up is done. The ignition coil, the fuel pump and filter , the computer , injectors do carbon up.

So when getting the tune up ask to have the injector cleaning done. The injection cleaner for the engine is from the dealer . They have a special cleaner . This is a common repair per Chevy to have the injection service done.

Good luck
